This was taken at a Creation convention in Phoenix in 1998 (or 1999 — I’m not 100% sure. I’ll have to look it up.)
This was back in the days before conventions were selling photo-op tickets.
Apparently the convention promoters hadn’t sold as many autographs for Leonard Nimoy as they had expected. So, as the autograph line was winding down, they were still trying to get people to buy additional autograph tickets (and they had a fairly large stack.)
Having already gotten his autograph, I waited until there were only about five people left in line, then I said that I’d buy a ticket if I could get a photo with him instead of an autograph. They said that was fine with them if it was OK with him.
It was.
