This collection consists of printed matter relating to World's Fairs and Expositions, starting with the The Great Exhibition in London in 1851. Though the bulk of the collection is made up of postcards, there are newspapers published at World's Fairs, advertising, travel information, and other materials, including a personal scrapbook of travel to the 1967 Montreal Expo. Some of the materials are originals from the exhibitions and some are materials about the expositions.

A 2016 addendum is comprised of wood blocks probably created as photogravures, of othe 1893 Chicago Exposition. There are 7 or 8 piece here. They were a gift from the Smith-Zimmerman Museum in Madison, South Dakota.
