This particular piece is a masterpiece by Lothar Klute: It consists of four glass panes firmly embedded in bronze. The tabletop, designed to resemble a flower blossom, appears to bloom and rises from the organically shaped, wrought bronze base. Lothar Klute's signature is prominently displayed on the base. The original certificate of authenticity from Lothar Klute is also still available. A specific bronze alloy enabled the artist, Lothar Klute, to forge the bronze. The glass was produced using a special melting process and custom-fitted to the table. This piece has an attribution mark, I am sure that it is completely authentic and take full responsibility for any authenticity issues arising from misattribution
