Vtg Birks Logo Pin Brooch + Box

Downsizing some of my Birks collection slowly. 😔 This is a neat vintage Birks logo pin: I have owned one before that was marked g/f for gold filled, but this is not marked. It is 1” by 3/4” Letting it go with one of my little cardboard boxes of the same era! It is in excellent vintage condition. A great piece to have with a Birks collection of fine items!
