Signed by Joe Sambito, Steve Lyons, and one other signature we were not able to identify. Please note that the handwritten Roger Clemens is not an authentic signature. It appears that it was written there to identify the cover subject rather than to deceive, but if you wanted to take advantage of our authenticity guarantee on this piece (see terms and conditions for details, and email with questions before bidding), it would have to be for a full letter, as that is the only way TPA's will authenticate it.
