Still as simple and effective as ever! This iconic logo is available in silver and gold metal versions, treated in a very modernist style. A rare brooch model, with mirrored geometry, signed in full on the back of the clasp. (I believe the signature dates from before 1980). I have another brooch from the same series for sale on the website, in silver and black, also with a modern design and mirror effect. Both are in very good used condition, see photos.
