This Greg Copeland Lucite Sculpture is marked 3/250, but I have not been able to find another like it on the market, though there are other Copeland's out there with some value. This 9 1/4" Square features one sheet of light orange and one sheet of dark blue with four clear orbs sandwiched between them. It was probably meant to be held along the edges so that one could experience the blending of colors at all angles, with the additional color of green (made from the mix of orange and blue). Gauging from the artist's work, I'd guess this is an early work. It is 2" deep, is signed and is in excellent condition. SOLD.
