This program accompanied a ceremony at the World Space Congress on the first day of the stamp's issue. No formal first day ceremony was held. These programs were distributed to World Space Congress attendees without a cancellation. Charles Vukotich, Jr. should be credited with having 40 programs, of which this is one, cancelled. Our thanks to Mr. Vukotich.
