2.5" with metal back and bar pin. Curl has name of maker Phila. Badge. Button surface has small bump upper right caused by insertion of the bar pin during manufacturing. Still the piece displays totally clean and pictures a young woman but we do not know any particular character she was inspired by. Her portrait is printed over the large numerals "191" referring to the 191st graduating class from "Central High Jan. '49." First we've seen and very graphic and attractive.
