WWII sweetheart pin, 1 1/2" x 1 3/4". I have seen a few of these with a sailor, but never one like this.
This man looks like Army Air Corps. He is pointing to a sign TAKEN within a heart, so you'd better not mess with his girl while he's away.
The pin is in fair condition, with some loss of the silver plating on the front and a little dent. The pin closes with a simple c-clasp.
