Discovery Island at WDW is no longer open, but these three items from the early 1980s are very collectible.

"Walt Disney World Discovery Island - A Very Special Zoological Park" guidebook marked (1983 WDP) opens up to reveal a feature story on the Osprey. Also included are an unused postcard 3.5x5.5 featuring Discovery Island with the Contemporary Hotel in background (WDP) and a WDW Discovery Island Excursion ticket stub (1980 WDP) There is a little wear around the edges of guide and card.
