On the cover of Vanity Fair in January 2009 was a very patriotic photo by Annie Leibovitz (so it may be more ironical).
But this photo is a quotation of a pin-up by the painter Rolf Armstrong (1889-1960). It dates from 1945 and was called "The Winning Combination". So it was a celebration of the end of the Second World War.
Maybe Leibovitz was just celebrating the end of the Bush era.
