Memorable to me, at least. I had a phone conversation with Kirby, and met him at San Diego. I talked with Stan a few times, worked on a book for his Excelsior Comics line that never came out, had lunch with him once. I met Carmine at a San Diego Con.
If I met Siegel or Shuster it would have been at a crowded DC holiday party, but I don't think I did.
