Stupell Industries White Iris Flower 2 pc Canvas Wall Art Set Design by Nan. Fill any space with Stupell Wall Art Sets. We create our stretched canvas to the highest standards. Using only the highest quality inks and canvas on Mimaki printers, we hand-cut and stretch each piece over a 1.5-inch thick wooden frame for hanging. As a result, the art comes ready to hang on the sturdy ledge with no installation required. Stupell Industries Wall Art is made in the USA.
