An Elston Howard signed 8 x 10 photo sells for about $100.-$200. Price will vary based on condition, and the type of authenticity that accompanies the signature. Photo composition, and appeal will effect the price as well. Part of the value will be determined by how well the photo displays the signature. The type of ink used, and how it stands out in contrast to the photograph will also effect the price. Sharpie would be most preferred for a photo. Larger and more desired pictures could sell for more. Collectors will pay more for inscriptions like "MVP", and pay less for personal inscriptions like "Good Luck Chuck"
