Years ago I bought a box of big glass-mounted slides, and was happy to find a few from Disneyland, 1955. They are from sometime within the first month of opening (the Chicken of the Sea pirate ship was not yet open). In spite of the fact that they were kind of a mess (magenta and splotchy), there were some great images.
Here is the intrepid spaceman known as K7. I hope his suit is climate-controlled, there's nothing like Anaheim in July/August. There's still a sense of innocent "gee whiz" fun in the Tomorrowland of the 1950's, and the feeling of a happy and exciting future for all of us. Say cheese, spaceman!
