What is a good website to find out how much music memorabilia is worth?

Question

My father-in-law got all four of the Beatles to sign a group photograph on their first tour of the states in the 60s. Just wondering how much it is worth today. The photograph is in excellent condition.

Answer 1

Ebay would be a good source for research. You would probably need to get the autographs checked by some experts to authenticate it.
