- Wood Engraving, Design for an Elevated Horse-Drawn Railway in New York, circa 1842 - The key to turning mass transit into rapid transit was in removing it from busy streets. One alternative was to build elevated structures that carried streetcars over city traffic. New York City, with its limited land and boundless population, developed a network of elevated lines that covered the length of Manhattan. Other cities, notably Chicago, adopted the technology too.

- Tooth Elevator, circa 1910 - Domestic horses require frequent dental maintenance to file down a tooth's sharp edges and prevent infections. Occasionally, however, a horse's tooth needs to be removed. This dental elevator helps veterinarians lift an infected tooth, making it easier to grasp with forceps to extract it.

- "Map Showing Chicago's New Subway and Elevated Road Connections," circa 1940 - This map introduced Chicagoans to the Chicago Rapid Transit Company's new subway lines, which would complement and relieve traffic on existing surface and elevated rail lines. When the CRT opened their subway lines in 1943, Chicago's rail lines, buses and streetcars were all run by separate, private companies; they merged in 1947 to become the municipally owned Chicago Transit Authority.
