The Galisteo blue artwork, set of 2 is printed, frame-less, free floating, tempered glass that was inspired by the French technique in which artist's painted the back of clear glass. Because of this when viewed from the front, the painting is brought to life under the depth of the glass. This beautiful piece displays an X-ray image of radiant blues. Two strong steel hangers are attached to the back of each product for quick and easy installation.
