Okay, spoiler tags away!! =) Enjoy!
You guys are right, it is a fan, but it's supposed to look like a souvenir fan from 1955. It's got art on both sides of each piece of the fan, with an attraction and the land it's located in. It says Acres of Fun and Souvenir of Disneyland on it (but with the Walt Disney Archives/D23 logo on the back) It's not quite cardboard strength, but is somewhere in between flimsy and durable. Each picture/attraction is on one side of five "swing-out" pieces of the fan. The "Acres of Fun" piece holds it together.
