- "A Signal from Mars March and Two-Step," 1901 - The concept of "life on Mars" did not begin in tabloid magazines.

- Stereograph, "The Planet Mars," 1909 - Americans loved stereographs -- millions were made from the mid-1800s through the 1930s. A stereograph consists of two offset photos that appear to have three-dimensional depth when viewed through a stereoscope. These images entertained and educated. Stereographs could transport viewers to distant events, exotic places, and even worlds beyond, like this image of Mars taken through a 40-inch telescope at the Yerkes Observatory.
