Disneyland: 50 Years of Souvenirs The happiest souvenirs on Earth live with Mark Atkinson, who has collected at least one item from each of Disneyland's 50 years of operation. By shopping at the park and scouring online auctions, he's amassed over 200 Goofy treasures. View-Master Discs let youngsters relive the thrill of Adventureland in 1956, while kids in 1985 got to experience the Magic Kingdom through Nintendo. Mysteries abound in the Haunted Mansion Secret Panel Chest, but the Indiana Jones Adventure Decoder Card explains it all. Back when the park opened in 1955, admission was $1 for adults, fifty cents for kids, and the Disneyland Fun Box and Official Frontierland Game probably didn't cost much either. Who knows what the prices would be in today's Disney Dollars. (in Entertainment > Amusement and Theme Parks)
