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.".
