Here's a custom T-shirt I had made for my son, a future UMSF'er.
On the front is a picture of an astronaut working on the Hubble. I tried to convince him he wanted one from the Moon, but he loved this picture the most. It was a real PITA, because the original version he glommed onto was low resolution, and it took more than an hour to tease the right one from NASA's website.

On the back he wanted a picture of a rocket launch, so I licensed one of the images of the New Horizons launch from Ben at http://www.LaunchPhotography.com to give him his "fix".

This will go well with his Spirit and Opportunity shirt. Gotta love CafePress!

I think he likes it because the astronaut is waving right at him!

Great idea...

Should there be a 'special' issue UMSF.com T-shirt with the new Sputnik logo?

Already mentioned in the logo thread. No. The time it takes to make stuff for cafe press, and the tiny tiny amount of cash that it generates - simply not worth it.
