According to some bio books, Lucille Ball also posed nude early in her career for the money. I can believe it, as she seemed laser focused on being in show business and willing to do whatever it took to pay the rent during that time.
She made most of her money from Star Trek (Desilu Productions), IIRC.
Even back in the day, I never looked down on women that posed nude for magazines. You do what you have to do to get the bills paid. Better than getting knocked up and going on welfare.
