I'm really excited to have a drawing made into a t-shirt by the brilliant folks at Turtlehead (use discount code "marc johns" and get 20% off until June 10th). They've done shirts by Keith Walsh, Adam Cruikshank, Will Bryant, Will St. Leger, David Shrigley, and many other terrific artists.
To be honest, I've been hesitant to do the t-shirt thing. I don't want to get to a point where I am drawing for the purpose of making products. But I like Turtlehead's approach. Besides, any organization that has worked with David Shrigley is tops in my books!
