This is a quad-fold brochure for the Gray Line Sightseeing Tour Busses. It’s dated 1976.
This brochure is centered on Orlando, which means all tours listed in the brochure start and end in the Orlando area. Destinations for tours are to all the larger attractions within a couple hour’s drive of Orlando: Walt Disney World, SeaWorld, Kennedy space Center, Cypress Gardens, Silver Springs, Busch Gardens and St. Augustine.
Interestingly, the one major attraction that’s missing is Circus World.
