Some of those incredible images and stories behind the decades of photos are in Crawford’s new cocktail table size book called ” Becoming” and the idea for it began when she and her team were looking ahead when Crawford turned 50 later this year.

“We came across an idea of doing a book to celebrate that and have something to look forward to instead of dreading turning 50 . So, the idea was to have 50 images that were iconic and represented my career but coupled with what I learned along the way to celebrate turning 50,” Crawford said.
