Letter One
March 7, 1964Letter Two
Dear Walt Disney,
I watch Woodywood Pecker every week and see you on it. I like it very much and so do my younger sisters. Would you please send me a picture of you and some of the characters. Thank-you very much. Well, I guess I'll go and watch Bugs Bunny.
From one of your true fans,
Wendy
WALT DISNEYLetter Three
April 6, 1964
Dear Wendy -
Even though Donald Duck, Mickey Mouse, Pluto, Ludwig Von Drake and the rest of our characters aren't related to Woody Woodpecker, I'm glad to know you like him because he belongs to my good friend Walter Lantz. And I know Mr. Lantz will appreciate knowing you are a fan of Woody Woodpecker.
I am enclosing the autographed picture of me and a couple of my friends which you asked for....and I'm sending your note on to Woody Woodpecker. Perhaps you will get a picture from him, too.
Many thanks for your letter...and all best wishes.
Sincerely,
(Signed, 'Walt')
WALT DISNEYLetter Four
April 6, 1964
Dear Walter -
As you can see by the enclosed....I get blamed for everything that happens in Hollywood!
However, this time it's obvious this little girl has her Walters crossed -- although I don't know how the hell Bugs Bunny got in the act.
All best -
(Signed, 'Walt')
