The very rare "ARGUS" design lamp by Düsseldorf artist Stefan Bumm was designed in 1985, the era of New German Design, in which the Cologne design group Pentagon also had its origins. 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, European Plug (up to 250V).The wiring of this item may be original and might need replacement, if not specified otherwise.
