NEW YORK (AP, 04.02.2009) — On buttons, posters and Web sites, the image was everywhere during last year's presidential campaign: a pensive Barack Obama looking upward, as if to the future, splashed in a Warholesque red, white and blue and underlined with the caption HOPE.

Designed by Shepard Fairey, a Los-Angeles based street artist, the image has led to sales of hundreds of thousands of posters and stickers, and has become so much in demand that copies signed by Fairey have been purchased for thousands of dollars on eBay.

The image, Fairey has acknowledged, is based on an Associated Press photograph, taken in April 2006 by Mannie Garcia on assignment for the AP at the National Press Club in Washington.

The AP says it owns the copyright, and wants credit and compensation. Fairey disagrees.

The article quotes competing opinions about whether this is fair use or not, with all the usual hair splitting.

There's an interview with Fairey where talks about all the different influences that guided his transformation of the image and how other people worked on his stuff. Which makes the fair use discussion even more absurd.
