Autographed photos of JFK have a tremendous interest among collectors. Those who collect presidential memorabilia want these pictures and as well as though who collect items associated with President Kennedy directly. Because photos of him are increasingly rare, and autographed ones even rarer, a signed photo with an authenticated autograph can be valuable. Authentication is the crucial phase. Without it, the picture has limited value. If the signature is deemed authentic, the value increases, and could increase at a steady rate if several people want to buy the photograph. A good auction house will be able to get the best price for the autographed photo.
