This original signature is guaranteed 100% authentic. the reason I can say this is because I was President of the Southern CA chapter of the American Fighter Aces Association for 20 years and we put on 46 symposiums, with over 200 Aces, 10 Medal of Honor Recipients. I was also on the National Board of Directors of the American Fighter Aces Assoc. 2004-2019 and an American Fighter Ace Honoree since 2011. I have traveled all over the United States visiting the Aces and authored the book, " Salute to the American Fighter Aces" along with being a lifetime member of the AFAA.
