Decade: 1970-1980 is a photography book showcasing Rennie Ellis' (1940-2003) contribution to photography and social history. With an introduction by film maker and Rennie contemporary Paul Cox and an essay by academic Susan Van Wyk, Decade highlights Ellis as one of Australia's most important chroniclers of the 1970s. The photographs, predominantly black and white, are drawn from a core selection originally made by Rennie from his own unpublished book, supplemented by other significant and iconic images from 1970 to 1980 drawn from the Rennie Ellis Photographic Archive and the State Library of Victoria Rennie Ellis collection. Many of the photographs are accompanied by extended captions written by Rennie himself, published here for the first time. Decade explores the cultures and sub-cultures of the seventies: the political upheavals, alternative lifestyles and counter culture, the women's movement, gay liberation, the new religions and cults, pop festivals, Vietnam and other protests, massage parlours, the disco scene, the blossoming of Australia's film industry, the new sexual freedom, Aboriginal rights, street festivals, the new theatre, fashion, drugs and the emergence of a decadent and hedonistic society that would later characterise the 1980s.
