This is a very hard 689 piece wooden jigsaw puzzle of a richly detailed 1928 diptych painting of a forest by Katayama Bokuyo. Our puzzle has mushroomy and leafy connectors and pentagonal pieces. Forest-themed whimsy pieces abound. Puzzle design by Tara Flannery and Jim Muller. This puzzle has a straight edge, but it's very difficult. Like all our puzzles, the pieces are laser-cut from 1/4 inch thick wood. Packaged in a pine wood box. Made in USA.
