Italian shock photographer Oliviero Toscani has released a new calendar at an unveiling in Florence, Italy -- a calendar featuring 12 penis close-ups in an ad for a group of companies that make naturally-tanned leather. The flamboyant photographer launched the calendar at an event in Florence also attended by famously well-endowed Italian porn star Rocco Siffredi, who said that people should "de-dramatise" sex and put an end to "bigotry". Toscani last year focused on women's genitalia for a calendar for the same Vera Pelle consortium, which brought censure from Italy's advertising watchdog.  Toscani is best known for his controversial ad campaigns for the Italian clothes maker Benetton, which itself courted controversy last year with a series of photo montages of rival world leaders kissing each other.
