Patrick spotted a photo of Grace Kelly on the front of a CJ-3A, which led me to find other photos. The photo shoot was part of a fundraiser for the Stevens School, the high school from which she graduated. Grace and the Jeep are in front of her childhood home. The photo was taken shortly after her sudden rise to fame in her first big movie role, High Noon with Gary Cooper. That set her on the path to fame and, several years later, to marrying Prince Rainier of Monaco.

This one was on Tumbler and included a caption that dated the event.
