Colorful mosaic and brass coffee table by the artist Berthold Muller. All of Berthold Muller's creations are unique. The mosaic tiles are arrayed in a beautiful abstract design, reminiscent of modern art of the period. The table top is in great condition. The border is made of solid brass. I have official proof of authenticity such as vintage catalogs, designer records, or other literature sources and take full responsibility for any authenticity issues arising from misattribution
