Let's compare some more flyers! I think these are "motel" flyers as opposed to "gate" flyers.
The front's of these flyers look pretty different, but they are similar overall. They both open up to a BIG photo poster inside with lots of fun pictures.
The first one is not dated but based on the attraction list (Pirates yes, Haunted Mansion no) I would place it as 1968.
This one is date stamped October 1973, with a print date of June 1973.
Tomorrow: More Main Street Electrical Parade!
