Egon Schiele's Four Trees painting is astoundingly beautiful, and one of his most famous paintings.
While our puzzle of Four Trees only has 79 pieces, we made it a fun challenge for adults by making it connectorless (but a frame of pieces keeps it from falling apart on you), which means you have to really look at the image to figure out what goes where.
So what was Egon Schiele thinking when he painted this? You can read a fun in-depth analysis of Four Trees at www.egonschiele.net/four-trees.
I have to admit this puzzles was a lot of fun and really a challenge. If you get one piece in the wrong spot it throws off the entire puzzles.
