This is an art puzzle, a true heirloom, where some of the thick wooden pieces have shapes that reflect the animals in the puzzle.  13 x 17in  482 made in the USA by Liberty Puzzles.  This is a custom print-on-demand product made of wood.  I love this puzzle so much I am ordering a small batch of them so that they come at a better price. Price includes tax and shipping!!  It usually takes at least three weeks to ship, but I have seven in stock to ship right now!  I will sign the box for you, too!
