These are some of the many small pen drawings on watercolor paper, as well as ballpoint pen drawings on blank playing cards. All of them are 2.5"x3.5." During this time, I often kept a small stack of watercolor paper in my pocket or waist pouch, and chipped away at them while traveling and working my table at events.
Many of the ballpoint ones were commissions for MTG fans on the back of proof cards, or for custom tokens.
