“Depicting women in chains was ubiquitous in suffrage cartoons from the 1910s, in which women sought to be emancipated by gaining the right to vote.
…Wonder Woman is bound in almost every one of her adventures, usually in chains. The bondage in Wonder Woman comics raised hackles with [publisher Max] Gaines’s editorial advisory board, but [Wonder Woman co-creator William Moulton] Marston insisted that Wonder Woman had to be chained or tied so that she could free herself — and, symbolically, emancipate herself.”
—From “The Secret History of Wonder Woman” by Jill Lepore
Can we please do away with the notion that bondage in 1940s Wonder Woman comics is nothing more than her creator’s sexual kink?
