no way to know. only an art expert can help there. a copy usually has very little value, unless it was signed by the artist and that signature was real. and at least according to the pawn stars, it usually needs a letter of authenticity to even assign a value. it could be worth a million dollars, or its wrapping paper for the next gift. hard to know, a pro would have to look at it and look at what that stuff is valued at.
