The is a rediscovered drawing from a college art class. The goal was to create a line study of an object. Not by simply outlining it, but looking closer at planes and structure.
As simple as it is I've always loved this picture. It has a sense of texture and mass without any shading. It forces you to see the object in a completely different way while still feeling like you could reach out and grab it. It is abstracted yet solid, tangible, and strangely elegant.
