I bought a set of Beatles autographs 4 years ago from Antiquities in Las Vegas. They are authenticated by Drew Max of AAU. After a bit of research on Max, and several rejections from auction houses and prospective buyers, naturally, I'm suspicious of the authenticity of these signatures. Antiquities gave me a money-back guarantee. I'm in Las Vegas RIGHT NOW (I live in San Francisco) and I'm trying to get a refund from Antiquities. Yesterday they gave me the cold shoulder. I'm going back in today hoping to talk to the owner. What am I to do? What do you guys think of the signatures?
