Found behind a brick wall in a Chicago apartment building in 1967........the one and only Traub. Dated to 1916, no evidence of exactly when/where it was built or who built it. 80-inch sidevalve w/ a 3 speed (HDs first sidevalve, 3spd, 80" was in 1936!!!)
The bike is an inspiration. If you haven't seen it....stop on by.
