I found this great vector drawing by Pawel Ochota called “Utopia.”
It sort of reminds me of one of the Myst games, or even scenes from Avatar. It also makes a great jigsaw puzzle for kids of all ages and sizes.
So I put in four extra versions for kids, ranging from six to 40 pieces.

Little Kids Puzzles:
6 pieces   15 pieces  
24 pieces   40 pieces  
Big Kids's Versions:
Easy   Medium   Hard   Tough  
(P.S. - The "101 New Jigsaw Puzzles for Kids" CD is still on sale for a little while longer.)
