This was obtained with retro jewelry.  I am not certain it is a vintage piece but very cute the same.  It is marked on the back but I could not make the stamp out.  He is about 2 5/8" in L from the top of his hat to the bottom of his shoes x about 1" across his shoulders.  He is accented in colored and clear rhinestones on his hat, face, shoulders and shoes.  He is in very nice condition.
