Laser cut plywood, interlocking with at least 70 figure pieces. Artist is Claude Monet. Chris Wirth has copied through computer graphics the wonderful figure pieces and basic cutting style of the famous Jones Family/Falls puzzles made in the 1930's which he inherited through his family. Since the computer controls the cutting, the figures are absolutely accurate. Cutting is much faster than with a traditional scroll saw, thereby allowing Liberty puzzles to be priced well below hand cut wood. Liberty puzzles also have the normal tightness of jigsaw puzzles. On the other hand, lasers employ a lot of heat burning the sides of the wood as they cut pieces, leaving a burnt order and possible discolor of the picture. You be the judge, but the price can't be beat!
