Of all Stooges collectibles, autographs are the hardest to value. Because there are so many variables involved, the only real way to know the value of what you have is to run it up the Ebay flagpole. Variables which will affect autograph value include the following factors(in no particular order):
1)full name or first name only sig (i.e "Larry Fine" or just "Larry", or maybe "Larry, 3 Stooges")
2)Inscription or just sig (i.e "To my friend James, Sincerely Larry Fine", or just "Larry Fine")
3)type of item signed(i.e photo, document, handwritten letter, album page, comic book, etc)
4)Uniqueness of item signed (common Columbia publicity still vs. menu from a famous Hollywood restaurant)
5)age of item (signed in the 1930's or 1970's? Presence of date?)
6)condition of item and sig (is sig bold and legible? Is piece in nice condition?
7) does sig look legit?
