Oftentimes, people would receive a letter from Ms. Lincoln saying that the President was happy to sign the item for the recepient when in reality, it was signed by a secretary. They did this just so people would believe that they received a real JFK autograph. It was done with good intentions, although it was very dissapointing for heirs to learn the truth many years later. Still, many people would point to a letter from Evelyn Lincoln as “absolute proof” that they had a real JFK autograph when in reality they did not.
In 2005, Christie’s actually sold one of these signed and inscribed photo’s by Jill Cowan for about $5000. Since then, i believe Christie’s realized their mistake and would never certify one of these again as authentic.
