This rare boat pin is signed “CA” with the distinctive arrow maker’s mark, which means that it was created by the Carl-Art Company. Carl Schraysshuen and Arthur Loercher founded this jewelry company back in 1936. The pin could be gold filled, but we have no way of testing it. It has 8 silver tone chains which create the sails of the boat. This pin is 4 ¾” long and 3 ¾” wide. This rare boat is in mint condition.
