Sample Autograph Signature:
American biographer, literary historian, and founder of the International Mark Twain Society.
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.
We do not have anyone who can authenticate nor value signatures.
Please contact registered autograph dealers for such evaluations.
