(FOX NEWS) DES MOINES, Iowa – The Marine Corps says it has begun investigating whether it mistakenly identified one of the men shown raising the U.S. flag at Iwo Jima in one of the iconic images of World War II after two amateur history buffs began raising questions about the picture.

The Marines announced its inquiry more than a year after Eric Krelle, of Omaha, Nebraska, and Stephen Foley, of Wexford, Ireland, began raising doubts about the identity of one man. In November 2014, the Omaha World-Herald published an extensive story about their claims and Saturday was the first to report the Marines were looking into the matter.

Associated Press photographer Joe Rosenthal shot the photo on Feb. 23, 1945, on Mount Suribachi, amid an intense battle with the Japanese. Rosenthal didn’t get the names of the men, but the photo immediately was celebrated in the U.S. and President Franklin Roosevelt told the military to identify the men.
