Twenty-Five Prints on the Block
I drew this at A-Kon, if I recall correctly. Several months ago we auctioned off the original. If you've got a copy of Schlock Mercenary: The Tub of Happiness you know that this picture is on p. 239, the last illustrated page (well... unless you paid to have me illustrate the blank page that follows...) 
By permission of the owner of the original, we did a run of 50 prints as "thank you" gifts for people who helped out at the Tub of Happiness ship-fest. The remaining 25 are up for auction now.
