Playskool Jigsaw puzzles,'Lets play grownup' and 'Sand and Water play'

I found these at Goodwill, no boxes, and no marking other than Playskool and their names: Sand and Water Play and Let's Play Grownup.

They have no tray, they have the exact same cutting pattern. Made in 1973, there were 20 different pictures and they seem to have come in a 6 piece or 8 piece cutting pattern.

I have plenty of wooden tray puzzles but these are the most unique of my children's puzzles.
