Pepsi asked Disney to build them a World's Fair pavilion, and Pepsi paid for it and put their name all over it. Joan Crawford slapped UNICEF on the billing to make it all seem charitable. UNICEF didn't pay a dime for any of it and had no creative input, but the UN staff was happy to take some charity checks from Pepsi-Cola. The US Committee for UNICEF did set up a little display near the exit however, and they sold their UNICEF Christmas stamps there. But it was really all Pepsi, all the time.
Ms. Crawford was not a stupid woman.
At the World's Fair it actually had a title that was perhaps one of the longest in Disney attraction history, even outdoing today's young Imagineers who slap colons and marketing junk onto every title.
