The show, which ran from April 17 to Nov. 19, 1958, was a huge hit in Brussels. People waited in line for hours to get in. The show was the most popular part of the Czechoslovak pavilion, which had over 6 million visitors. Walt Disney, who saw the show on July 4, 1958, wanted to buy the worldwide rights to the concept so he could install a version in Disneyland. Communist authorities, though, did not allow it.
