For the 24th annual event held September 30, 2007, the official poster artwork was a photo featuring well-known LGBT and BDSM community members in festive and fetish attire including Sister Roma "as players in an innovative version of the culturally iconographic" "The Last Supper" by Leonardo da Vinci, complete with table draped with the Leather Pride flag and "cluttered with sex toys, whips, and various (BDSM) restraints". The image by FredAlert was used on the official event guide and produced as collector's posters that were displayed throughout the city as advertising for the event. Some conservative religious groups criticized the image as anti-Christian and blasphemous, although media outlets noted that parodies and homages of the Last Supper painting like Renée Cox's "Yo Mama's Last Supper" are numerous, including ones by "The Simpsons", "The Sopranos", Phish, "That '70s Show", Robert Altman (in the film "MASH") and the Boston Red Sox. Chris Glaser, a gay clergyman and interim senior pastor at San Francisco's Metropolitan Community Church agreed that "they are just having fun" with both the painting and the notion of 'San Francisco values,' stating he thought it was "tastefully and cleverly done".
