Note: The internet is inundated with autograph forgeries of John Wayne along with other high value autographs.  One hint is they are priced way below actual value (because forgers never bought them).  Be very cautious and ensure whoever you buy from guarantees it for life, BUT also guarantees it will pass JSA or PSA authentication.   Some unscrupulous dealers will respond with "we don't agree with JSA or PSA". Hence they do NOT offer a guarantee if they disagree with the expert independent authentication. .   Also, if they are NOT members of a reputable autograph related organization like the UACC, then they are NOT held accountable by anyone if you buy a fake autograph from them.   UACC Registered Dealers are held to a very strict code of ethics and are required to refund any autograph that is deemed not genuine by a leading authentication service.  Visit UACC.ORG is see if your autograph seller is listed in the UACC Approved Directory of Registered Dealers.
