Here are my two prized original comic art pages:
The first one is a page from Scud: The Disposable Assassin by Rob Schrab. He pencils his pages on graph paper, then traces and inks them on vellum. Very unique. I was so jazzed to be able to buy a page this summer.
The second is a page from Sam and Max: Freelance Police by Steve Purcell. I bought that one two years ago from Steve at Comic Con. I still don't have it framed.
Also, be sure to check my Comic Con post below! I updated it with pictures.
