All are copyright 1935. Published by Whitman. Each is 3.5x3.5" with stiff paper covers and 160 pages. Titles are: "Jungle Jim, Sappo, Benjy, Smilin' Jack, Streaky, Nicodemus O'Malley, Little Joe, Freckles, Alexander Smart, Bobby Thatcher, Broncho Bill, Dinglehoofer and his dog Adolph". While this is a complete set as issued, the "Dinglehoofer" title is a rare error as printed and contains the complete contents for "Nicodemus O'Malley".

Rarely offered as a set, made even more so due to the rare printing error on one title. An instant collection.
