|This pin set was originally sold through the Disney Catalog in 1997 and is individually-numbered. With the start of pin trading, unsold units were brought out of the warehouse and sold at the WDW parks through late 2000 when they eventually sold out.|
There are 12 individually-numbered pins in the set, all featuring Mickey Mouse, commemorating each country represented in the World Showcase as well as a very large Centerpiece pin of Mickey holding flags in front of Spaceship Earth.
Pins in this set are the Centerpiece (#2622), Canada (#5719), China (#5721), France (#3290), Germany (#3289), Italy (#5718), Japan (#5720), Mexico (#3285), Morocco (#12674), Norway (#5722), United Kingdom (#5723) and United States / USA (#5724).
I have seen this set both as pictured and with the smaller pins in a circle around the large Mickey/EPCOT pin. Both are numbered.
NOTE: There are open stock editions of the country pins (listed as "Open Stock Epcot Stamp Series"): They are not numbered and made of a much lighter-weight material.
