GPGC T-Shirts as collected by Dr. Middleton and others and archived by Josh Brown. We are missing many many, so if you still have your old t-shirts and they are missing from this archive, please contact me (Josh Brown) at principal-at-gpgc-dot-org. Also, if you have any comments at all about the shirt designs - especially the earlier ones, like who designed them and why, please email them to me too.
