Do you need to see how this puzzle works before you buy lots of sets? Do you need to pitch the idea of using a Community Puzzle to your boss? We understand completely and have just the solution- the Community Puzzle Jr! The Jr set contains 4 large center pieces, 8 border and 4 corner pieces. This puzzle is exactly like the full size one (only much fewer pieces) so you can use it to test your markers, paints and other materials on it too.
