Stupell Industries Ducky Days Landscape Wall Plaque Art Design by Petal Prints Design. Our wall plaques start as high-quality lithograph prints mounted on durable 0.5-inch thick MDF wood. Each piece is hand finished and comes with a fresh layer of white foil on the sides to give it a crisp, clean look. Plaques arrive ready to hang without installation and come with removable plastic corners to keep them from damage in transit. Stupell Industries Wall Art is made in the USA.
