So sweet! Ca., 1950's black enamel dog on a spring that bounces in the red enameled frame of a window. Aka "How Much is that Doggie in the Window?". With the enamel condition being too good, I believe this piece has been reworked and I can see that the hinge portion of the pin mechanism was replaced at some point in time. Still, it was just too darling to pass up and wears very well! 1 1/2"
