Troels, Up front I would tell you to never buy anything on the net that does not have at least TPA's from PSA/DNA, ACOA, BECKETT, or JSA….I have no knowledge of any worthy authenticators in Europe….From what I remember, you are a beginner at this. I did see a JSA sticker and card for a Richard Dreyfuss, 8x10 photo that sold for $25 on the net. Just watch what is for sale and do not be in a hurry….With luck you can find something with the sticker on the back, just make sure it comes with a corresponding card. Also keep in mind there are people out there who are selling copies of autographed and TPA'd items for cheap…..They are not real autographs….David
