Am looking for some advice. I have been given a signed picture of Heath Ledger as the joker. Its framed and incased with the frame is a joker card which was used on the set of the making of the Dark Knight. I have the certificate of authentication to go with this picture. I am looking to either sell this picture but not sure what to price it at. Does anyone have a clue??

You might get more bites if you post a picture.

Would probably be a fake, as no stills were released until WAY after his death.
