Mary Hartline and Super Circus, the show that made her a star, were a few years before my time.
Super Circus ran from 1949 to 1955. This paper doll was a Kellogg's cereal promotion. I wonder how many boxtops kids had to send in? It's a static cling doll, so no tabs on the outfit, just rub the outfit on the doll. The cling is still there.
