The kiss goodbye; 8-piece. Series number 190-22. Reads "Ages 2 to 4 years."
Dopey with the others looking on, 9-piece. Series number 190-1. "Ages 3 to 6."
Here's the same basic Dopey (190-01) but with an alternate color scheme and slightly divergent puzzle cuts. The rending of Snow White and the other dwarfs is different. No age range is listed, an indication that this puzzle is probably older than the one above.
The Old Witch and Snow White, 20-piece puzzle. Series number 375-01. No age range on this one either.
