Nineteen-year-old Robert Whitman had the good fortune of snapping Prince Rogers Nelson in Minneapolis in 1977, way before he became an international star, and way before "Kiss" or "Purple Rain."
At the time, Prince has just been talent-scouted by Owen Husney and Gary Levinson, and they needed some promotional shots.
The agent played the track "Soft and Wet" in his car to the young photographer and there followed a shooting both in the streets of Minneapolis and in the studios. These shots have now been gathered in a limited-edition book entitled Prince Pre Fame.
In this book, Robert Whitman celebrates the fortieth anniversary of this meeting with a star in the making and the early beginnings of his career.
Photos were you can see Prince smiling are pretty rare but there a few of them scattered within the 648 images. The book also contains a touching poem by Spike Lee.
Prince Pre Fame is available through Vero and will set you back $142 (£106) or $744 (£557), depending on the edition you choose. 10% of the profits will be donated to amfAR, The Foundation for AIDS Research.
