The scene from the 1955 film caused a stir from the day it was filmed, and decades later, it's still causing controversy.
The 17-ton "Forever Marilyn" statue, which towers 26 feet above Michigan Avenue, shows the actress in the provocative pose, and it even shows her underwear.
"I'm an elementary school teacher, and I find it offensive," said one woman.
Among those who didn't like the provocative pose at the time was Joe DiMaggio, Monroe's then-husband. An outraged DiMaggio is said to have stormed off the set.
