Apple IIGS T-Shirt?

I work in a school near Cupertino, and we get offered "camps," "schools," "colleges," etc. for various computing products. Usually it's for training teachers, students, staff, or all three on new Apple products. Often you'll get t-shirts, mugs, sweaters, or whatever as promotional items. That looks like an old school sweater from the same type of program. At some point I'm willing to bet Apple held a "IIgs College" workshop for learning how to incorporate the Apple IIgs into curriculum.
