I saw a claim that the popular "Rosie the Riveter" poster is:
1) Incorrectly called by that name
2) Originally a union-busting poster
en.wikipedia.org/wiki/We_Can_D… confirms that Rosie the Riveter was a song originally fully decoupled from the poster. The association between the two came decades later.
While not directly and exactly union-busting, it was part of a series of posters intended to inspire workers to keep calm and keep working for Westinghouse and for the war. It wasn't a symbol for women power, merely an acknowledgement that women were there too.
All that said, of course these days it can mean whatever people want it to, and it's clear that a mind of today often first sees it as a feminist empowering image.
