Luther Blissett (1994–) is a collective identity that was begun by Italian anarchists in 1994. The idea is that anyone may call themselves Luther Blissett (a name they took from a famous and still-living footballer). Luther Blissett has since done a large number of extravagant, anti-spectacle media stunts and has collectively written an international bestseller, Q (which, like the rest of their work, is freely downloadable). When controversial anarchist Hakim Bey was set to visit Italy, Luther Blissett published a book as if it were written by Hakim Bey, which included, among other things, a speech by Josef Stalin. It met with critical success and quickly sold out. Only later was it revealed the the book was a fake.
