Here is an extremely rare (I have never seen them before) pair of Hans Hansen cufflinks in the Functionalist Art Deco style, most likely designed by Karl Gustav Hansen, who made the company so famous in the 1930s with his early modernist designs. These cufflinks feature the Hans Hansen trademark backs.
