Madcap Molly
Madcap Molly, 'the do-it-all dolly,' was produced by Kenner and sold around 1971-72.
Madcap Molly was a mostly flat plastic toy with pins at her shoulders, wrists, and attaching her legs; when wound up, she would walk along pushing one of three accessories which accompanied the doll: a shopping cart, a ski, or a scooter.
Not technically a 'doll,' the toy came with a variety of hats and stood about 12 inches high.
Madcap Mollys are not highly sought after vintage toys, but are nonetheless usually difficult to find with all pieces and joints intact.
