It is made of high-quality brass and chrome. The finish to the rectangular shapes of the base is really nice. The top is made of smoked glass, adding very nicely to the design. The combination of shape and material gives this highly recognizable piece a very luxurious style! This piece is attributed to the mentioned designer/maker. It has no attribution mark and no official proof of authenticity, however it is well documented in design history. I take full responsibility for any authenticity issues arising from misattribution
