Check this out, just found while browsing the Vintage Computing section on eBay:

Pretty great condition copy of Legend of Kyrandia, with the box almost entirely shrinkwrapped still. I guess the owner only sliced the shrinkwrap at the top of the box in order to get the game disks/manual out, but kept the rest on to keep the box in great condition. Well, that's my guess anyway.
