I think it ought to be documented ,if there are seller's that are "CLEARLY" deceiving folk's & have made a career out of peddling un-marked signs ,and use various names to hide there real identity!"THATS A BLACKMARKET OPERATION" ,some have been addressed about there business practice & have made the decision to proceed selling unmarked signs,with no respect to the collector community!I think it would be a great source of info to the community!It really surprises me that nobody has had a infringement case brought on them yet,or.... been investigated by the us attorneys office,that is willful infringement for profit!I personally believe the bigger operations are making enough money to turn some heads at the attorney generals office!It's no differt them these folks that are knocking off Rolex's, Tommy Hilfiger ,Purse's,Perfume.....ext it's big business for some! there day will come!
