Diptych Set -Empire Art Direct''s collection of printed, frame-less, free floating, tempered glass was inspired by the French technique of Verre Eglomise in which artist''s literally 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. In collaboration with Albert Koetsier, this beautiful piece displays an X-Ray image of indigo calla lilies and a lusty blue tulip. 1 strong steel hanger is attached to the back of each product for quick and easy installation.
