Designed to bring the intricacy, craftsmanship, and beauty of classic wooden jigsaw puzzles to new generations of collectors, Liberty Puzzles are a return to the golden age of puzzling. All of their puzzles, including the uniquely cut "whimsy" pieces, are made from 1/4" wood and carefully crafted in Boulder, Colorado. For serious puzzling, there's nothing quite as satisfying as the PLUNK of dropping a wooden piece into place!
