There are a few more tips you need to know when you are buying an authentic autograph photo. You have three photos of Christian Bale to choose from. The three autograph photos of Christian Bale in a suit, Christian Bale in a Rescue Dawn scene, and Christian Bale as Batman. A photo of Christian Bale in a suit is not going to be popular and command as much money as the Batman photo. There may be a lot of Christian Bale fans but there are more fans of Batman especially since Batman is one of the most iconic comic book characters. The Rescue Dawn photo with Christian Bale is more valuable then Christian Bale in a suit but the Batman photo is still more valuable than both photos. Basically if you are going to buy an autograph based on worth and demand you are going to pick the Batman photo. The more fans you have the higher demand you have which makes an item more valuable. Which photo are you going to pick?
