This just in from Gunnar Andreassen:

[If you are not aware of it already: An item for sale at Heritage now, that might interest you: A Roy Disney Signed Contract Regarding Merchandising, 1932 with Kay Kamen, three of totally 12 pages are found in the description.]

This is an incredibly important piece of Disneyana / Disney history: The first contract signed between Disney and Kamen. This also means that the date of the signature of the contract mentioned in my article in the magazine Twenty-Three (July 1, 1932) is off by two days, since the contract is actually dated June 29, 1932.
