I’m not a motorcycle guy per se but Indian motorcycles are an iconic name in motoring history as well as being timeless pieces of Americana.
Indian made bikes from 1901 to 1953 and in the 1910s, they were the world’s largest motorcycle manufacturer.
The 3′ x 2′ steel sign would have hung in a garage or dealer from approximately the 1930s. Despite the condition issues (some pitting and some surface rust) it was found in good overall shape. The heavy gauge steel is straight as an arrow and the factory drilled screw holes are clear.
