18x72 3D Pro Vintage L21C Canvas 2-1/2" #DO-1872

True 4:1 Super Panorama Proportion - 18x72 Size

This dramatic 18x72 size is in the 4:1 Aspect Ratio.

The 4:1 Super Panorama proportion has gained interest with a lot of artists, providing even a more dramatic and eye-catching compositional format. The unusual proportion provides the artist with a unique perspective with which to tell their story on canvas. This proportion is called a "polyomino proportion on the order of 4", or a linear tetromino object.

3D™ Pro 2.5 Stretcher Bar • 1/2" Canvas Clearance

1/2" Canvas Clearance is the space between the Bar and the canvas. Generally speaking, more clearance reduces the risk of the canvas touching the wood and creating unsightly lines during painting. Our design provides the optimal clearance so as not to impact your painting, but still leaving enough wood to the maximize strength of the Stretcher Bar.

• Produces a 2.5" deep stretched canvas (Actual depth is slightly thinner)
• 1.25" wide Stretcher Bar
• All Bars have an exclusive groove on the inside perimeter of the frame to which cross braces and Diamond Corner Braces attach
• Solid Ponderosa Pine or Fir from the Pacific Northwest

Solid Wood is Archival - Finger Jointed Wood is Not

We only use Solid Wood to build our Stretcher Bars because a solid piece of wood will last indefinitely. When we speak of archival value, it's not just the paint you use and the quality of your canvas and ground, even the wood choices manufacturers make are part of the archival process.

The principal reason manufactures use finger jointed wood is reduce cost, not increase archival value. Wood constantly grows and shrinks when the environment becomes hotter, or colder, or more humid, or more dry. Because finger jointed wood is made-up of multiple and varied pieces of wood, with varying grain patterns and densities, they each absorb and shed moisture at varying rates, which works on the glue joints that hold them together, causing the wood to bow and the joints to eventually fail, and certainly not consistent with increasing the archival value of your artwork frame support.

As a manufacturer, we do our part to conserve as much wood as possible, and still provide a quality made product that will out-perform any other in the marketplace.

18x72 2.5" Deep Edge Heavy Frame Offers Maximum Support!

• Drawing depicts the exact frame construction, not the proportion
• 2.5" Deep Edge K2 Heavy Stretcher Bars are precision machined with a unique double tongue-and-groove corner joint that provides rock-solid torsional rigidity that resists warping or twisting, which is an important benefit for such a deep edge canvas
• Two parallel 3/4" thick super strong keyable braces (3.25" wide) provide excellent frame support for this 18x72 size - Braces are permanently installed in the frame, but canvas tension may be increased by tapping-in the keys or wedges that slightly expand the size of the frame
• The Stretcher Bars have an proprietary utility groove on the inside perimeter of the frame which is used to attach braces and other optional frame supports
• The Masterpiece braces feature an exclusive system that allows you to increase the tension to the middle of the frame, where the tension is needed the most; it's so unique it earned us a patent
• To increase canvas tension: 1) remove any staples in the corners and those that retain the brace keys in the middle, 2) tap all of the expansion keys further into their respective slots, 3) tighten and re-staple the canvas in the corners

Canvas Tension is in Your Control

In dry climates or air conditioned environments, the lack of moisture in the air causes wood frames to shrink and the canvas fibers to narrow and elongate making the canvas more slack and resulting in a loss of canvas tension. In some instances, the canvas could have waves on the surface resulting in an unsightly viewing experience.

Our 3D™ Pro 2.5 professional frames provide the functionality for you to slightly expand the size of the frame in the corners and the middle of the canvas, thereby increasing canvas tension all across the surface. The difference between a loose canvas and a tight canvas is just 1/8" of an inch, so a small adjustment using our corner and brace keys makes an important difference in canvas tension.

• Helps to prevent waves that occur in a loose canvas
• Increase canvas tension by tapping-in the corner and brace keys
• True professional class canvases make it possible for you to adjust the canvas tension

Cross Braces Make it Tighter

A tightly stretched canvas on an un-braced frame overpowers the Stretcher Bars causing them to bow inward and thereby lose tension. Sometimes that bow can expose a space in picture frames.

When a canvas is stretched on a properly supported frame, the cross-braces prevent the Bars from bowing thereby achieving maximum canvas tension. To increase the canvas tension even more, simply tap the corner and brace keys further in their slots. Properly supported frames provide you with the control over the canvas tension of your canvas and painting.

Sustainable Environment Promotes a Sustainable Economy

The use of lumber from sustainably managed forests is not only environmentally responsible, it also helps to support the economy and preserve jobs in the forestry industry. By choosing products made with sustainably sourced lumber, consumers can help to ensure that these industries remain strong and sustainable for years to come.

Specially Dried and Heat Treated Lumber

We source our wood from a select group of top-tier environmentally conscious lumber mills in the Pacific Northwest. These mills specially dry and heat-treat the lumber to our specifications, resulting in about half the moisture content compared to wood from typical home improvement centers or lumber yards. This process makes the wood stronger, reducing the likelihood of cracking, splitting, or warping. While the wood we use comes at a higher cost, it ensures a more dimensionally stable end product. This stability is crucial for crafting fine professional canvases that support your invaluable art over time.

MuseumWrap™ Stretching Technique

With more than a half a century of American engineering, Masterpiece® designs and builds its own proprietary stretching equipment that enables us to produce the finest and most tightly-stretched canvas on the market.

Celebrating a rich legacy since 1965, Masterpiece® is the gold standard for artist canvases in North America. Every canvas is a potential magnum opus, a union of creativity and quality materials that can transcend time. Your choices today impact your art's tomorrow, so invest in the best for a lasting legacy.

I find that I painted my own reality, not what others wanted. ♦ Frida Kahlo

In a world rife with external influences and pressures, Frida Kahlo stood defiantly steadfast, painting her truths without compromise. The worlds she crafted on her canvas were solely her own, free from the influence of critics or contemporaries. Many artists grapple with this challenge, balancing personal vision with external expectations. As artists, we too have faced moments of doubt, moments when the voices of others threaten to drown our inner muse. Yet, Kahlo's unwavering commitment to her truth encourages us to prioritize our unique narratives and perspectives.

While the art world may at times be driven by trends and popular demands, Kahlo's legacy stands as an enduring testament to the timeless appeal of authenticity. Her fearless portrayal of her reality underscores the idea that true artistry lies not in conformity but in courage, in the bravery of painting one's unfiltered soul.
