Mouseketeers Fan Club Card

[Bluesman]

I found a mouseketeers fan club card in really nice shape. It's got all the original mouseketeers on it. The back of it has a hand drawn Donald Duck on it and is signed by Roy. Does anyone know if there is a value to this? If anyone knows anything about this card please send me an email. slangbein@hotmail.com
Thanks,
Steve
