Audrey Hepburn's timeless style continues to inspire, most recently with the release of a new book by photographer Bob Willoughby titled Bob Willoughby: Audrey Hepburn, out today. “She took my hand...well, like a princess, and dazzled me with that smile that God designed to melt mortal men's hearts,” said the shutterbug, who followed her from her career start in the 1950s to the height of her My Fair Lady fame. The new tome features 280 pages worth of shots of the private actress, many never before seen. Preview Willoughby’s photos in the gallery—her memorable smile prominently featured—and find the book on amazon.com for $70 (on sale now for $44). For Hepburn memorabilia collectors, there is also a limited-edition volume available at taschen.com.
