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 railroad buffs. An unique and educational gift item. 100% cotton. Measures 23 x 23 (in inches) square.
