If you can't track this company down, try remembering the design and getting it printed by another company. We use Metropolis, which is a local company for us, but I believe they'll ship shirts anywhere. All you have to do is describe the design as well as you can and their artists will draw it up. Their website is
http://www.metrogreek.com. Look through their design gallery. There are some Pi Phi shirts on there that my chapter (FL E) has actually had made.
