This study is remarkable in the amount of life it brings to a simple drawing. The image may have been a source of inspiration for Escher's famous drawing of a hand drawing another hand; there has also been ubsubstantiated speculation that this may have served as a study for hands in the the Mona Lisa. This seems unlikely, but the sketch is striking.
