Tijuana Bibles

Tijuana bibles (also known as eight-pagers, Tillie-and-Mac books, Jiggs-and-Maggie books, Jo-Jo books, bluesies, blue-bibles, gray-backs, and two-by-fours) were palm-sized erotic comics produced in the United States from the 1920s to the early 1960s. The earliest Tijuana bibles, particularly early "Tillie and Mac" and "Maggie and Jiggs" stories, are dated to 1925. Their popularity peaked during the Great Depression (1929 to 1939).
