Vintage & Rare NY World's Fair Keychains His & Hers Official Souvenir 1964, pre-owned in great condition. The NY World's Fair was a cultural touchstone for many American Baby Boomers who visited the optimistic exposition as children a few short years before the social and political turmoil of the Vietnam War era and the massive cultural changes of the later '60s. The fair gave many attendees their first ever interaction of any sort with computer hardware; corporations demonstrated the use of mainframe computers, computer terminals with keyboards and CRT displays, teletype machines, punch cards, and telephone modems in an era when computers had rooms of their own in the back office, decades before the advent of personal computers and the Internet. Great gift for collectors and baby boomers.
