Last year, I purchased eight binders full of slides from someone's vacations in the 1970s. I estimate there are close to a thousand slides, some commercial, and some taken by the vacationers. I have began to slowly digitize the interesting ones, in order to preserve these folks memories for a couple more years. The scanned slides will be on my Flickr account.
While there are no Disney ones, I did find some examples of things which inspired attractions in Disney parks. This is the first: A shot of the true Matterhorn, followed by the scale version in Disneyland.
