first Disneyland admission ticket Roy Disney
Geoff Boucher of the Los Angeles Times has a fascinating story about the Disney Archives:

After Walt Disney died in 1966, his grieving staff sealed his office suite in Burbank, and even as work proceeded on “The Jungle Book” there was anxiety that the company’s past might be brighter than its future.

Four years later, those worries deepened as key executives approached retirement, including Walt’s older brother, Roy O. Disney. That’s why, in 1970, the company handed the key to Walt’s still-sealed office to a former UCLA research librarian named Dave Smith, who was sent into the chamber to learn its history.
