Although this article is mostly about the "Primevil World" section of the 1964 World's Fair Ford Pavilion, it also has some interesting information about the pavilion's origins which I had not read before. Ford was trying to set themselves apart from Chevrolet marketing. (I posted a correction about a picture miscaptioned as "Ford Mustangs" which are not Mustangs. No update thus far.)
Walt Disney's love of trains and miniature dioramas has influenced many of the attractions at Disneyland. One example is a section of the Disneyland Railroad that takes guests millions of years into the past, Primeval World.
