Cyberfest Postal Covers and Arthur C. Clarke Letter

Cyberfest was a weeklong celebration of the birthday of the HAL 9000 computer, a character in the novel and movie 2001: A Space Odyssey (both written by Arthur C. Clarke and Stanley Kubrick), which was held at the University of Illinois and in the cities of Champaign and Urbana in January 1997. Arthur C. Clarke participated in the festivities by appearing via satellite video link at the gala event at the end of the week and also appeared in a film with Roger Ebert made for the event. Judy Tolliver was working in the University's Department of Computer Science and was the originator of Cyberfest as well as serving as one of the event's organizers.
