In 1943, she collaborated with photographer Frank Powolny for a regular studio photo session. During the shoot, she took several photos in a tight, one-piece bathing suit. One particular pose consisted of Grable's back being to the camera as she playfully smiled looking over her right shoulder, the reason for this pose was the fact that she was in fact several months pregnant with her first child. The picture was released as a poster and became the most requested photo for G.I.s stationed overseas. Grable's photograph sold millions of copies, eventually surpassing the popularity of Rita Hayworth's famous 1941 photo.
