Originally published in 1929, these color maps have had several revisions. They consist of linen-backed paper with the corrections pasted directly onto the map. Wear and rubbing at extremities, especially near corners, spine only connected at spine ends. Stains and soiling on covers, paper cover label with some paper loss on right side as well as extremities. Attached by paperclip to the first map is an order form from the Sanborn Map Company. Laid-in at the end are some torn pages of additional notes. Maps heavily wrinkled due to the pasting of the corrections.
