The highly recognizable image is one of the most parodied photographs in history. Anti-war activists in the 1960s altered the flag to bear a peace symbol, as well as several anti-establishment artworks. Edward Kienholz's "Portable War Memorial" in 1968 depicted faceless Marines raising the flag on an outdoor picnic table in a typical American consumerist environment of the 1960s. It was parodied again during the Iran hostage crisis of 1979 to depict the flag being planted into Ayatollah Ruhollah Khomeini's behind. In the early 2000s, to represent gay pride, photographer Ed Freeman shot a photograph for the cover of an issue of "Frontiers" magazine, reenacting the scene with a rainbow flag instead of an American flag. "Time" magazine came under fire in 2008 after altering the image for use on its cover, replacing the American flag with a tree for an issue focused on global warming. The British Airlines Stewards and Stewardesses Association likewise came under criticism in 2010 for a poster depicting employees raising a flag marked "BASSA" at the edge of a runway.
