This relief by Hermann Goepfert, between OP an ZERO, suffered water damage with severe discolouration and formation of tide lines. To maintain the original fabric instead of replacement - as was considered by the owner - some miracles of cleaning had to be achieved.
The object had to be completely disassembled. The partly bent metal reflectors had to be reshaped and cleaned as well.
Joint Project with Dipl.-Rest. Laurence Becker.
