I just sent out the first GPT poster yesterday to our contest winner and I have to say, it's pretty sweet. It's 11x17 full color and very nice, printed on poster-quality paper - I'm going to be selling them for Ten Bucks a pop if you're interested.
You'll have, all at once, the entire Guinea Pig Theatre library, collected, to hang on your wall - and that's pretty sweet. I have to imagine that it's, at least, a very cool conversation piece. Email me, if you're interested at starr226(at)gmail.com.
