 The original plan of San Francisco Science Fiction Conventions, Inc. was to hold the convention at the futuristic San Francisco Marriott Marquis, designed by the noted architect Anthony J. Lumsden, which is topped with a jukebox shaped glass tower that makes it look like a skyscraper from a Flash Gordon comic strip by Alex Raymond.This building is a notable example of futurist architecture.However, the hotel backed out of the contract when a more lucrative larger convention wanted to schedule there on the same weekend.
