Three-dimensional supporting frame
A three-dimensional supporting frame includes a blank. The blank includes an image receiving surface, a back surface opposed to the image receiving surface, a center portion defining a perimeter, and at least three foldable extensions extending from the perimeter. Each of the foldable extensions includes no less than four folds to be folded toward the back surface to form the three-dimensional supporting frame. A tab line is scored in one of the folds of each of the at least three foldable extensions, the tab line to be released to form a tab to be secured to the back surface when the folds are folded. An adhesion promoting layer is present on the back surface at the center portion.

7. The three-dimensional supporting frame as defined in claim 1 wherein a surface of the tab to be secured corresponds with the image receiving surface, and wherein the frame further comprises an adhesive on the surface of the tab.
8. The three-dimensional supporting frame as defined in claim 7 , further comprising a release liner removably adhered to the adhesive on the surface of the tab.
9. The three-dimensional supporting frame as defined in claim 1 wherein the adhesion promoting layer has a coat weight ranging from about 0.01 gsm to about 5 gsm.
10. An art canvas, comprising:
a blank, including:
an image receiving surface;
a back surface opposed to the image receiving surface;
a center portion defining a perimeter;
at least three foldable extensions extending from the perimeter, each of the foldable extensions including four folds folded toward the back surface to form the three-dimensional supporting frame; and
a tab scored in a third fold of each of the at least three foldable extensions and secured to the back surface, wherein the tab has a corner radius scored in the third fold of each of the at least three foldable extensions;
an adhesion promoting layer on the back surface at the center portion, the adhesion promoting layer increasing adhesion between the tab and the back surface;
an adhesive adhering respective portions of the back surface and each of the folds that is furthest from the perimeter;
an image receiving medium having an image printed thereon; and
an adhesive adhering the image on the image receiving surface at least at the center portion.
