Theme Parkeology (theem pahrkŏl’ə-jē) = the study of details, minutiae and history of theme parks. Akin to the archaeological study of human habitation, theme parkeology looks at the often layered and detailed surroundings. Theme Parkeologists relentlessly pour over the tiniest scraps to glean any information about an area of a theme park, past or present. (Term first coined by the original Theme Parkeologist, Jeff Pepper at 2719 Hyperion.)
We can get an idea about the type of marketing and graphics that the parks were using back then.
