These Wood pieces make a fun addition to any decor! They are 13.75 x 11.75 x 1/4 inch thick birch wood with Stephanie's art printed on them and a satin finish top coat. The subtle wood grains within each piece show thru the lighter colors in the art. A wood piece on the back gives them a floating 'off the wall' appearance. They can be used indoors or outdoors out of direct sunlight.
