after doing more research on the internet this is what i came up with
This souvenir was created to help children enjoy their visit to EPCOT by collecting stamps and stickers from the eleven countries featured in the World Showcase. The kit contains one EPCOT passport, 11 sheets of “stamp” stickers from the World Showcase countries, a vinyl storage pouch and an EPCOT button. As children travel around World Showcase, they can apply the “stamp” stickers to their passport, and even have their passport stamped at a designated location inside each Pavillion.
