The Giant-Size Marvel blog found this awesome print from 1996, drawn and hand-colored by Marvel artist Marie Severin and featuring herself taking on the publisher's toughest heroes and villains. The color version was limited to 50 copies, but there were also 400 black-and-white prints, which you can see in the link.

I'm guessing Severin sold these at conventions, and I love that she included herself in the drawing.
