With a name as distinct as Rolly Crump, you either remember the name, or just haven't heard it yet. He is one of the last original Imagineers and architects of Disney World, and of the Disney marquee at the 1964 World’s Fair

this is the famous Gypsy Cart designed by Crump, and made by Thomas Kuntz @haxanthrobo with the help of @horriblyeclectic who made and hand painted the banners and tent for it, based on Crump's original drawing from the late 60s

He started as an assistant animator in the Disney films “Lady and the Tramp” and “Sleeping Beauty,”
 the became an imagineer, and helped design the rides at Disney World, helped develop Walt Disney’s World’s Epcot, worked out effects for the Haunted Mansion with Disney’s master illusionist Yale Gracey, and worked on It’s a Small World Disney marquee for the 1964 World’s Fair. That's right, he built an exhibit draw (if that's the right word) for the last well known Worlds Fair!

He also designed the tiki gods and goddesses for the Enchanted Tiki Room.

and was a key architect in the 1967 Tomorrowland redesign
