Isn't it just a t-shrit with that SSE image on it with the monorail line wraping around it. Its based on the poster that says "The 21st century begins October 1st 1982".
I have no knowledge of any kind about the 25th, but as soon as I heard there would be *any* limited edition t-shirts, this design was the very first I thought of. Actually, I just kind of *assumed* that this would be at least one t-shirt. I mean, it has to be the coolest of all the EC logos that got much viewing.
And I agree, if there was more EPCOT Center merchandise, I would actually buy it. I buy at most one Epcot item a year right now. While I like Disney a great deal, how many spatulas, coffee pots, etc. can I really use? I consider myself an EPCOT Center addict. (Maybe I should consider changing my screen name.) Most of the Epcot stuff they sell, while not that much, is pretty generic. Or am I the only one that feels this way?
By the way, how many people remember the passes and merchandise bags that Disney used at EPCOT Center prior to the Disney Studios opening in 1989? I have several bags from mid-1980's, several "admission media", and several maps from the time. They bags were cool because they were exclusive to EC, oh and also made of paper. They had most of the countries and FW pavilions depicted on the bags, and Magic Kingdom was not even mentioned. I realize it's easier and cheaper to print bags for all 4 parks, especially given there are 4 parks, but it was so cool having bags to distinguish each park.
I agree - a surprise is nice. I'm glad the design is being kept secret. I'll just be glad when its finally released so I don't have to keep quiet anymore.
