Comment here for a chance to win

Untitled, a photo by Ape Lad on Flickr.

Leave a comment under this post for a chance to win this drawing (suitable for framing, stacking, folding, or filing). It's drawn in black ink on a piece of white paper (don't let the fancy flickr filter fool you).
This is the drawing that became this design, and again, you don't have to vote for the shirt design for a chance to win.
I'll choose the winner a week from now, and be sure to log in with your google account or some other way so I know how to contact you if you win. Don't leave your email address in your comment, that sort of thing flies in the face of internet decorum.
Finally: thanks! Have a great weekend!
