These are Busch Gardens postcards from 1975 to the present. This is the era when the park became a fully-fledged theme park, arguably the 2nd or 3rd such park in Florida (Disney World’s Magic Kingdom being the first and Circus World being the other 2nd or 3rd).
SeaWorld had also opened by this time, but it was much like Busch Gardens in the mid-1960s. It had plenty of animal attractions and shows, but other than the Sky Tower, it didn’t have any big rides. SeaWorld didn’t really become a theme park until the mid-1990s with the addition of thrill rides.
