This comprehensive guide to discontinued Disneyland attractions also includes a meaty section (at the bottom) on Disneyland ephemera. From old aerial photos to internal memos to early advertising for corporate-sponsored attractions (e.g. Richfield’s Autopia), there’s a lot of old paper here. And of course don’t miss the comprehensive information on decades of favorite attractions like the PeopleMover, Captain EO, The Country Bear Jamboree and the Submarine Voyage.
