Amazing cabinet photo by A.W. Judd (1846-1929), Chattanooga, Tennessee. The subject matter alone makes this a great photo, but what makes it even better is the Carhartt heart shaped button on the engineer's overalls. Carhartt used this style button from 1900-1930. Judd established his Chattanooga photography studio in 1877 at 828 Market Street. More of Judd's work can be found at the Southeast Tennessee Digital Archive.
