I got possession of one of the spares of the shirt with this on it last night (the Minn-StF archives kept the best copy and however many copies they thought they needed). I had one of the original ones, back in the 1970s, but wore it out long ago. It was one of my favorites.
This particular one also has “Video Services” on the back, so I’m particularly happy to get this one now (a year ago, in time to wear in Kansas City, would have been even better, but I don’t think we knew we even had these in the t-shirt collection back then).
This may have been the first local fannish t-shirt; I don’t remember Minicon shirts before this for example.
They were made by local fan Jerry Stearns (now of Great Northern Audio Theater), as I remember it silk-screened by hand at home rather than through a commercial producer. I don’t know where the artwork came from; it doesn’t seem to be signed. Does anybody remember that?
