Forgeries

[jeffbrow_cpjupljj]

I strongly suspect that someone is selling forgeries of a famous author's signature.  I have no proof, but as a book collector I have a good eye and all the signatures are exactly alike and do not look authentic. I have not bought anything from the seller, but they have listed many of what I thinkn are forgeries. Does anybody know what to do about this?  I think it is imporatnt that people hold one another accountable on this type of issue.  Ebay requires a lot of faith from buyers and sellers, and don't lilke the idea of anyone taking advantage of this. If anyone can point me in the right direction, I would appreciate it.

Thanks,

JB
