This collection contains lithographs of New York City streets, buildings and other structures drawn and printed by Ernest Born during the period 1930-1931. The suite of 15 completed images are New York City subjects originally contracted by a London art house; but, due to the 1930's depression, the transaction was not completed and the project remained in the Born family archives.

The lithographs are titled as follows: "Brooklyn Bridge" "Late Afternoon" "Battery Place" "East River Bend" "New York Public Library" "Grand Central Station" "Park Avenue and Lincoln Building" "Trinity Church" "Wall Street" "Garment Center" "Foundation Construction" "6th Avenue Elevation" "Jeannette Park Curve" "Bank of Manhattan and US Treasury" and "Frankfort Street.".
