2D Sphinx Puzzle

This puzzle is one of many recursive type puzzles, where the goal is to replicate the shape of the pieces themselves in larger size. In this case four pieces shaped similar to the outline of the Sphinx are to be combine to make a larger outline of the Sphinx identical to the individual pieces.
