I have been keeping an eye on a few Muhammad Ali items that come with a hologram from Muhammad Ali Enterprise on them. Well the items might come with a hologram that looks like one of theirs but in fact it's not. Someone is making these holograms and putting them on fake items no of them come with the certificate with the matching hologram. Here are a couple of examples so unfortunately buyer beware when even buying a Muhammad Ali item with a Muhammad Ali Ent hologram.
