That looks more realistic, but is probably also a fake. If someone is going to go to all the trouble to get a Moz autograph, he or she is not going to sell it, most likely. It's probably one of the hardest autographs to get on the planet.
Oi, I assume it's probably a joke, but please don't associate the Brazilian Moz Cover guys with these scams.
They clearly state on their website that they are a tribute to Moz, and the duo doesn't profit from recordings or merchandise.
I can vouch for that!
