Photo from WorldCon 1961, featuring editor Forrest J. Ackerman standing behind two young cosplayers with his hands on their shoulders. On the left is Joni Cornell wearing some kind of future bikini over tights, with blonde hair. On the right is a shirtless young man in green facepaint, pants and a long scarf/cape. Absolutely no idea what these people are dressed as.

Ellie Turner and Karen Anderson in sci-fi babe cosplay at WorldCon 1961. They are standing in a rather dull hotel function room with wood paneling and floor, one is wearing a green gauze and sequins belly dancer-esque ensemble and the other is in a purple vest and loincloth over a flesh-colored leotard.

A black and white photo from Seacon (Worldcon 1961). Two men in costume (alien? ancient Greek?) grasp hands in the foreground, while a third man stands in the background, hand on hip.
