Gary Shipman is a self taught artist and writer. Shipman has been nominated for Eisner, Harvey and Russ Manning awards. When I saw that Gary Shipman was regularly doing sketchcard (and other) commissions on WhatNot, I decided to try to get one. As you can see above from Shipman’s riff on Sly Stallone as Jack Carter, I succeeded.
You can see more of Gary Shipman’s art at his webpage, his Instagram page and on his Whatnot stream.
