Sample Autograph Signature:
American science fiction writer, TV and screenwriter, multiple winner of Hugo and Nebula awards
Please note that while we have reason to be confident that the signature
is genuine by virtue of its source, it has not undergone
any expert examination or verification. Accordingly, TomFolio does not
guarantee the authenticity, nor can a comparison of a signature with
this example exclude the possibility of an autopen, a printed
facsimile, or a reasonably capable forgery.
