| 1975 | 5/24-5/26 | Equicon 75 | El Cortez Hotel | Guests included the entire main cast of Star Trek. photo Date verified from con's PR#2 Briggs adds: the name derived from the convention supposedly being on the Equinox. There were several Equicon's in L.A. before and after, at the Vernal and Autumnal Equinoxes. McCoy writes: The first four [1971-1974] were run by Bjo trimble in Los Angeles. She allowed a group of STAR San Diego fans, headed by Jean Graham, to run the 1975 convention, combining it that year with the other LA convention Bjo ran, called Filmcon [hence, Equicon 75/Filmcon 3]. |
