I have a photo signed by Joe Cobb from the older shorts. It has Joe in a field together with (I believe) Farina. They've both got their dukes up. Behind Joe is a sign that says "Democrat side", behind Farina is a sign that says "Republican side". I couldn't find this shot online.
I met Dorthy/Echo 2 years ago and she's still sharp. She has no bad recollections from making the films.
