The Dormilon gray 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 a black and white X-ray image of a pink eucalyptus bush. One strong steel hanger is attached to the back of each product for quick and easy installation.
