It won't answer all of your questions, but may help you home in on more specific information you're seeking.
As "rating," value, and popular subjects, I think you will find photos are far more subjective than most other areas of sports collectibles. There is no price guide, and no widely accepted grading system. It's all about the content and originality, and though popular subjects mirror other areas of collectibles, all photos of a given player are not created equal.
Basically, I think you will find that the further you go down the rabbit hole, the more you will realize how impossible it is to address any of your original questions in a succinct manner. As I read each of them, I think to myself, "Holy crap, where do I start."  |
That's definitely a start, thank you.
Edit: Just checked Amazon and the book is like $100... wow.
I picked this up more for the signature than the photo (I figure that since it is not really a "baseball" picture since there are no uniforms and the like it is probably not something that adds a ton of value) but it got me wondering about this area of the hobby which I know nothing about.
