These are done in permanent marker on 9 x 12 inch thick archival paper. A single character sketch is $30 for black and white, $50 for color. I'm currently accepting pre-ordered commissions for NEW YORK COMIC-CON. Pay now, pick it up from Table K8 at any time. I don't have e-commerce set up for this so just email me to get the ball rolling.
After the convention, I'll start offering commissions by mail. Woo hoo!
