This was the lead summer press release story from Disneyland Publicity for Summer 1968.
It describes in a little detail the new Tomorrowland features and “Most exciting of all new Disneyland attractions is the fabulous ‘Pirates of the Caribbean’”.
It’s four pages with the first being on News from Disneyland letterhead. This is obviously the file copy as it is annotated by multiple people. This was probably a big deal for Disneyland Publicity at the time.
