13th Witness (aka photographer Timothy McGurr) is dropping a T-shirt today in collaboration with Pittsburgh shop 412, and it's the only piece you should be copping today. The piece pays homage to the Pittsburgh Pirates, and was done to celebrate both the Steel City and McGurr's recent showing in 412. If you're in the Pittsburgh area, swing through 412 tonight to meet McGurr and purchase the piece before the limited run is all snatched up. If you're not in the Pittsburgh area, no worries, you can cop the t-shirt online here.
