This is a 379 piece wooden jigsaw puzzle of French painter Isabelle Plante's painting of a stack of books by great thinkers, titled "La Connaissance". Our puzzle features knowledge-themed whimsy pieces by Kathryn Flocken, including silhouettes of some great thinkers (see our blog for the legend), surrounded by "normal" looking puzzle pieces with knob connectors (click on the small picture below the main image to see example pieces). Packaged in our standard pine wood box. Laser-cut from 1/4" thick wood. Made in USA.
