This just in from Brad Abbott:

[I'm conducting research on the sponsors and lessees at Disneyland, from the parks opening in 1955 until the introduction of New Tomorrowland in 1967. I'm interested in how these companies/individuals came to find out about Disneyland, their decision process in becoming a part of the park, and how both parties were able to benefit (or not) from the relationship. Anyone with information/documents about the early corporate sponsors and small businesses and restaurants at the park that they'd be willing to share can contact me via e-mail (bnabbott@sbcglobal.net).]
