3D 1893: Columbian Expo Stereoscopes

Just stumbled across the New York Public Library's Digital Archive and its amazing Robert N. Dennis collection of stereoscopic views. It includes a bunch from the 1893 World's Columbian Exposition in Chicago, which I'm loving, as I'm in the middle of reading Erik Larson's Devil in the White City, a great account of the history of the Expo and how it was a hunting ground for America's first serial killer, H. H. Holmes.

If you're interested in Holmes, the National Geographic special, Madness in the White City, does a good job of summarizing his story and the Expo. There's also an indie documentary, H. H. Holmes: America's First Serial Killer, that is pretty low budget but well intentioned, although it doesn't have much on the Expo.
