World's Fairs or International Expositions are large-scale exhibitions that highlight technology, agriculture and other innovations of national or cultural significance. The 1964 New York World's Fair was held in Flushing Meadows, New York from April 22, 1964 to October 18, 1964, and then again from April 25, 1965 to October 17, 1965. The theme was "Peace Through understanding." This item is an advertising place mat printed in two colors with drawings of scenes from the upcoming world's fair.

The Pennsylvania Railroad (PRR) was chartered in 1846 to complete an all-railroad network across the state. Between 1855 and 1874, the PRR underwent rapid expansion and emerged as one of the two largest railroad systems in the region east of the Mississippi and north of the Ohio. In 1910, the PRR entered Manhattan through tunnels under the Hudson and East Rivers. This collection consists of flyers and a brochure for Pennsylvania Railroad special fares or trains.
