Silver & Blue Facet pendant by Louis Weisdorf for Lyfa, 1960s Denmark

An iconic lamp designed by louis weisdorf for the danish lamp manufacturer lyfa. 1960s, early version. The lamp is like a 3d puzzle, with eighteen identical metal elements, each a long punched and curved piece that fits into the next, and the next, until a cylinder is formed. Light comes through small gaps between the pieces, revealing the tones inside while filtering the light. Signed.
