Colmor "Supermarket" Dexterity Puzzle, c 1930s

This is one of three Colmor dexterity puzzles I'm listing, all from the 1930s or so, and the graphics of which I just love, perhaps this one most of all! The woman and her cart sit on top of the stocked supermarket background, which makes getting the three metal balls into her basket--in less than one minute as instructed--a little more challenging than one might think! Pretty fun, and a great gift for the super super-marketer.

5" x 3 1/2" x 1/2" and in very good condition.
