Adamson, Joy: 'Born Free - A Lioness of Two Worlds' [Collins & Harvill, May 1962]; 'Living Free - The Story of Elas and her cubs' [Collins & Harvill, 1st ed., 1961]; 'Forever Free - Elsa'a Pride' [Collins & Harvill, 1st ed., 1962]. All with dust jackets and all signed by the author on the title pages. (3 vols). Nice set of George & Joy Adamson's account of their pioneering conservation project involving three generations of lions in Kenya's Serengeti in the late 1950s/early 1960s. The first volume formed the basis of James Hill's 1966 Oscar-winning movie of the same name.
