Signed photos are images that have been autographed by a celebrity, athlete, or public figure. These photos often feature the individual in a memorable pose or moment, making them valuable to fans and collectors. The signature adds a personal touch and can enhance the photo's worth, especially if the person is well-known. Collectors often seek signed photos for their memorabilia collections, and they can be found at events, auctions, or online marketplaces. Authenticity is crucial, so many signed photos come with certificates of authenticity to verify that the signature is genuine. Popular subjects include actors, musicians, and sports stars.
