I have found THE BEST website for vintage Disneyland photography.
the link is
www.davelandweb.com
Go to his Disneyland photography section, and you'll find thousands upon thousands of photos of current photos and vintage pictures of Disneyland. I was ABSOLUTELY amazed when I came upon this website. Pictures of nearly every nook and cranny can be found!
Although the photos aren't "perfect", the main reason I enjoy this site is to take a glance at past attractions!
The site is easy to navigate through, and I think you'll be pleasantly surprised!
