Not all that many years ago, comic book conventions were mostly Boys' Clubs. There were San Diego Cons where the only women on the premises seemed to be Mrs. Jack Kirby and maybe June Foray. June, by the way, will be a featured guest at the 2004 Comic Con International in S.D. and I'm going to put together something spectacular (I'm not sure what yet) for the occasion.
Anyway, one of the things that has changed about conventions in the last decade or two is the large percentage of ladies who are present, many of them quite spectacular in appearance. There's a photographer named John Chennavasin who goes to glamour-type events and takes pictures of the models, and he's lately taken to visiting Comic Con International with his camera. Here's a link to some photos that he took at the 2002 convention and here are pics from the 2003 con. [CAUTION: Selecting some of the other links on his site could plunge you into sectors of the Internet where ladies cavort without clothing. You will be one click from porn instead of the usual two clicks.]
