Gronda Mirror Hanger by Luciano Bertoncini for Elco, 1970s, Set of 3

Gronda modular coat hanger mirror by Luciano Bertoncini for Elco, 1970. Mirrored glass, 3 modules, very good condition, the back of one module has a hole that does not affect the solidity of the structure, not visible once mounted on the wall.
Each module measures 20cm wide and 200cm high. 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
