I Bought this on E-bay several months ago and wondered if you remember doing this button art and if there were any "behind-the-scenes" stories humorous or otherwise that you might recall about it? Thank you,

Not much I remember. Toronto con, as I recall. If it's the one I am thinking of, my first and only trip to Toronto. Pleasant enough. Canadian fans have a way of asking all the same annoying and insulting questions, but doing it in a very polite manner. . . .
