I had t-shirts (one white and one light blue) custom-made for me by cafepress.com which I wore during Mousefest in 2006. It consisted of the screen names I've used on various WDW fan communities, such as Disboards, Passporter, and Tagrel, with Mickey heads down the right side.
Jim, were you able to just purchase two? I always find with those things that you need to meet a minimum -- like 6 or more. That'd be great if Cafepress can do one at at time!
