OffWorld Designs has had a presence at many WorldCons over the past 25 years.

We love the World Science Fiction Convention, so we're honoring the last 74 WorldCons on this shirt. Starting with NYCon I in 1939, they are all listed on the back, like a concert t-shirt of sci-fi literary goodness.

Find it on a Unisex T-Shirt here: Unisex T-Shirt
