Several women inspired the image of Rosie, rolling up her sleeves to help out the men in the World War II effort. There was also a song

All the day long,
Whether rain or shine
She's part of the assembly line.
She's making history,
Working for victory
Rosie the Riveter.

The original poster associated with Rosie The Riveter was actually a separate meme, based on a photo of a Michigan factory worker, but the various images melded in collective memory.
