Dutch art deco brutalist copper hammered triangle mirror, 1920-1930s

A lovely hand hammered copper dutch art deco triangle mirror, presumably school of amsterdam, 1930s. This gorgeous mirror could also be classified as brutalist. The copper has been polished a little as the mirror had completely faded to black over time. The mirror can be hanged pointed down or upwards ( please do keep in mind that for the moment the lamps is fixed for point down, please see pic for hanging thread ).
