BASYE, Va. (AP) — Bernie Boston, a newspaper photographer best known for his iconic 1960s picture of a Vietnam War protester placing flowers in soldiers' gun barrels at a rally, has died. He was 74.

Boston died Tuesday of a rare blood disease at his home in Basye, where he retired in 1994 after working for The Los Angeles Times, The Washington Star and the Dayton Daily News. His death was announced by the White House News Photographers Association, for which he served four terms as president.

Boston's photograph, "Flower Power," was a runner-up for the Pulitzer Prize. He took the picture at a war protest in Washington on Oct. 22, 1967.
