Antique Hand Fans

Looking for information/age ect.

I purchased a collection of hand fans from a woman and know nothing about them, just simply saw them at a yard sale and paid $40 for an entire box of old hand fans. I have a photo bucket account with pictures of most of the fans. I would really appreciate anyone with knowledge of hand fans to contact me as I know nothing about these fans and need help identifying them. I have some bone/ivory fans as well which are pictured in: http://s1291.beta.photobucket.com/user/mooseysworld/library/?view=albums

Thank you in advance to anyone who can help or even point me in the right direction.
