Photographs signed by Jessica Alba bring a decent price in the collectibles market. Certain retailers offer them at prices ranging from around one hundred dollars to a little more than three hundred. The actual value of the autographed photo is determined by the authenticity of the autograph, and the popularity of Jessica Alba. If the signature has not been authenticated, its value is very low, maybe around five to seven dollars. Value for her signed photographs also increase as her popularity rises, most notably after a successful film or upon receipt of an award. The price can be driven up during this period of popularity by selling the photograph in an auction setting, rather than at a set retail price.
