50s vintage children's puzzles, tray puzzle lot great old illustrations, fuzzy wuzzy animals

Lot of early 1950s vintage cardboard tray puzzles with some really wonderful illustrations of pets and baby animals - these are so colorful and fun!

The whole lot is shown in the first photo - six puzzles in all, all complete, though a little worn from play. They'd make kitschy cute wall art, or great display pieces.
