The Lad and the Lion is an adventure novel by American writer Edgar Rice Burroughs, written in February 1914. His working title for the piece was "Men and Beasts." It was first published as a three-part serial in All-Story Weekly in the issues for June 30, July 7, and July 14, 1917. The story was the first by Burroughs adapted to film, the movie appearing about the same time as the print serial. Despite this distinction, the story did not appear in book form for over twenty years; only after a remake of the film appeared was the first book edition published, by Burroughs's own publishing firm, Edgar Rice Burroughs, Inc., in February 1938. The text was apparently expanded for book publication, as certain incidentals of the story reflect the political situation of Europe in the late 1930s rather than the mid-1910s. The book was reprinted by Grosset & Dunlap in 1939 and Canaveral Press in 1964. The first paperback edition was issued by Ballantine Books in September 1964, with a second appearing from Ace Books in May 1974, reprinted in June 1982. Source: Wikipedia (en)
