That internet archeologist Bill Burns has discovered it’s still possible to view Michael Bernstein’s old Rotsler.com dedication site on Archive.org, with images.
Rotsler’s drawings on restaurant dishes are most nostaligic. They remind me of the 1974 Westercon where Bill impersonated AWOL guest of honor Phil Dick at the start of the banquet, and later entertained fans at nearby tables by drawing on their bread plates. (So far as I know, the committee was never billed for all the disappearing dishes.)
I assume the examples on Rotsler.com were drawn in later years because Ken Forman is listed as the owner. But it isn’t as if Rotsler didn’t do this performance more than once…
