Borsalino Fedora Hat

A vintage brown fedora hat made by Borsalino in Italy. It is made of felt (from what animal I do not know though it is likely beaver). It is marked "G D" on the inside of the rim, that may be a designation or the initials of the craftsman who made the hat. The dimensions of the outside are 11" deep by 10" in width by 4 3/4" in height. The head hole's dimensions are 7 1/2" by 6 3/4".
