This double-sided 79-piece abstract wooden jigsaw puzzle has abstract curvaceous puzzle pieces to keep abstract minds busy. The same image appears on both sides (rotated), making this quite difficult. It is said that this 1912 painting by German Expressionist August Macke was a homage to Johann Sebastian Bach. All our puzzles are made of layers of hard and soft woods, and are roughly 1/4" thick. Comes packaged in a small box with a magnetic clasp.
