Blue Boar Cafeterias was a chain of cafeteria-style restaurants based in Louisville, Kentucky. The first Blue Boar was opened in 1931.[1] Once a major presence in metro Louisville, it is still remembered for its old downtown location on Fourth Avenue near Broadway. During the 1930s, Guion (Guyon) Clement Earle (1870–1940) served as advertising manager. He was the brother-in-law of Frank Kennicott Reilly (1863–1932) owner of the Reilly & Lee publishing firm of Chicago. Mr. Earle was well known to the customers of the Blue Boar Restaurant through the witty jottings he created which appeared on the Blue Boar's menus. A decade earlier, Mr. Earle had served as the Superintendent of Loveman, Joseph & Loeb in Birmingham, Alabama, where he published a literary review entitled "The Bookworm".
