This sizable map was created by George F. Cram who served in the U.S. Army during the American Civil War. After the war ended, Cram joined his uncle Rufus Blanchard's Evanston map business in 1867. Cram's map offers a complete depiction of the railway systems that passed through Missouri and is believed to have been created in 1906-1907. In the lower left hand corner is a key explaining the map's contents including census data, counties, county seats, cities, post offices, railroad stations, villages, etc.
