I think that my favorite old photos of Disneyland are the ones you find on View-Master reels. Through the magic of stereoscopic photography, you get a perspective that you can't get any other way. And the older they get, the more fun it is to (re)capture that "you are there" feeling.
Stereoscopic photography uses special double-lensed cameras, thereby replicating the two images received by your two eyes and producing a pair of photos that provide a 3D image when seen through a special viewer, or even "free viewed" without any device at all if you're adept at the skill you use in order to see "magic eye" images.
As an interesting historical note, many Abraham Lincoln photos were taken as stereographs. There are less than 135 known photos of Lincoln, and only nine of them were marketed originally as stereographs, but many "regular" photos of him are simply the left or right side of photos shot with a stereoscopic camera. Stereoscopes were still a bit of a novelty in the 1860's, and photographers sometimes found it more profitable to print up one side of the stereoscope and sell it as a conventional portrait. Sometimes the stereoscopic secret was not discovered until much later, when a sharp-eyed observer noticed minute differences between photos thought to be identical, and it was discovered that they were actually right and left sides of a stereoscopic image. The two could then be recombined and the stereo effect recovered. Some of those lately-recovered 3D images are among Lincoln's best-known portraits!
