At a kinkier-than-average book launch last night, painter and writer Danny Moynihan introduced his new monograph Private Collection: A History of Erotic Photography 1850-1940 (Other Criteria, $100) - a compilation of naughty pics garnered by him over the last 25 years. Art dealer Jay Jopling, critic Nick Hackworth and model Laura Bailey all turned up at the Hix Oyster & Chop House in Farringdon to be duly treated to a saucy burlesque act on the bar.
