Sheet Copper (old Bisbee) Kay Robertson Coll.

Item Description

A sculptural, folded, bent sheet of native copper from the famous mines at Bisbee. The blue-green chrysocolla and clays on the nubby copper add a colorful contrast to this artistic two-sided specimen with striking 3-dimensionality. Ex Kay Robertson Collection # 2! and probably acquired in the 1950s or earlier! Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record). Classic old-time and UNCOMMON sheet copper from Bisbee.
