Gofer Service Awards, 1995. Pencil, colored pen and gel pen on 8.5 x 11 copier paper.
Wow, this one's the oldest so far. Very much created on the fly. We had so many apparently suicidally helpful gofers at Anime America 1995 that I felt that we needed to give them something. My sister had a small laminator, so they were photocopied and laminated, and given out to the volunteers.
I think we gave out 16 of them. I'm not sure.
The mere fact that I still possess this flimsy scrap of copypaper is amazing.
