Wow!! Unbelievable photos, wonderful post!
Some quick comments:
1) Atencio has one heck of a signature!
2) Interestingly, the "Epcot 25" logo in the display case features the interlocking "25," with the bottom line of the "2" connecting with the swoosh of the "5."
This variation was NOT used on park maps or special merchandise 10/1/07.
However, I personally pioneered this interlocking design element upon the creation of my very first "Epcot 25" avatar on Monday, October 24, 2005, a good two years before the 25th Anniversary. It was subsequently used in many fan-created avatars/t-shirts/logos/etc. created in the run-up to the anniversary.
Just wanted to point that out. (Disney. :lookaroun )
