Chicago's own Jay Ryan, The Bird Machine himself has a couple of shirts with Patagonia. I saw a tiny thumbnail and poof, it was so obvious who did these. It's a perfect match. I stopped by his studio a bit ago and I think his work and studio is quite great. I like the fact that his dad works there with him packing prints for orders.
