Sanborn Atlases were originally made in the 1920's and rather than make a new atlas every year the company sent out updates in the form of paper which was cut and pasted on each page depending on new developments etc. Sanborn Atlases were large, the scale was an inch for a 100 feet. It is hard to tell with the Sanborns when they were last updated. Many of the atlases are not marked as to the exact year. They were used till the early 1960's.
