The Library of Congress has an incredible archive of film footage from the Spanish American War.
This presentation features 68 motion pictures produced between 1898 and 1901 of the Spanish-American War and the subsequent Philippine Revolution. The Spanish-American War was the first U.S. war in which the motion picture camera played a role. These films were made by the Edison Manufacturing Company and the American Mutoscope & Biograph Company and consist of actualities filmed in the U.S., Cuba, and the Philippines, showing troops, ships, notable figures, and parades, as well as reenactments of battles and other war-time events. The Special Presentation presents the motion pictures in chronological order together with brief essays that provide a historical context for their filming.

Here's an interesting concept: Truetype and Type1 Fonts that are sets of wargaming and roleplaying figures instead of letters. Because they are, like all fonts, scalable, you can print them at whatever size you prefer.
Among the font sets are superheroes, pulp adventures, space opera, Ironclaw roleplaying figures, treasure, scenery and starships.
