Relive the Hobo days with this Hobo Codes Poster. It is unclear exactly when hobos first appeared on the American railroading scene. To cope with the difficulty of hobo life, hobos developed a system of symbols, or a code. Hobos would write this code with chalk or coal to provide directions, information, and warnings to other hobos. Now you can interpret the secret code or lingo of the Hobo! A must-have for all the railroad buffs. An unique gift item. This 11 x 17 (inches) poster is on antiqued heavy stock and will be shipped in a protective cardboard tube.
