Who Collects Autographs? Kaiju & Otherwise?

This topic came to mind as I went to the Hollywood Collector's Show in Burbank yesterday. While there, I obtained signed photos and posters from Noel Neill (Lois Lane), Jerry Maren (the Mole Man with the Electrolux raygun in Superman and the Mole Men (1951)), Traci Lords and Marilyn Chambers (the Ivory Snow girl). They were there in person.
Others I've obtained include Jonathan Frid (Barnabas Collins), Kirk Alyn (the screen's first Superman), Sarah Michelle Gellar (Buffy), Hurricane Ryu, Haruo Nakajima, Ken Satsuma, Ronald & Nancy Reagan, Richard Nixon, Don DeFore, Clint Eastwood, Red Skelton and others.
Who about you all?
