One of the least photographed structures and area within Disneyland was the Black Light Corporation of America Rainbow Hall of Enchantment Mineral Hall located in Frontierland next to Natures Wonderland Railroad. This photo is probably the best one that I have seen. I did a quick search and found that the Black Light Corporation of America was just a distributor for Ultra-Violet Products in the California area. To me the idea that a local company could afford to sponsor a whole shop is kind of stunning. Today I am sure that it costs millions of dollars to have your name at Disneyland on a shop or an attraction. I have done a little photoshop work and lightened the image to show at least the inside of the shop. There was definitely a lot of signage in the building. And I love the girl and boy looking in the camera in the lower right hand corner- Are we in the Photo?
