I had a chance to attend D23's preview of the Archives exhibit at the Bowers museum. It was fantastic. There are many pieces you've seen - but also many you haven't. Along with each subset of the exhibit there is a staff blurb posted where the Archives team member explains a little about that subset. There actually is quite a bit to read. The exhibit covers studio history, theme parks (a great display of Haunted Mansion tombstones and the hitchhikers), movies, costumes, props, toys, and even from some related films and TV where you wouldn't think Disney played. Some fantastic art I had not seen before from films like Johnny Tremaine, Darby O'Gill, Bedknobs and Broomsticks, etc. They are also presented several topic discussions while the exhibit is at Bowers. A short drive from the Disneyland Resort.
