Do you know who Gotta Have It uses to ok stuff? (As their stuff usually doesn't come with PSA or JSA certs). The reason I ask is that they have alot of MJ stuff in their upcoming auction. I'm not as confident with Global's COAs lately as I've some Springsteen's they've ok'ed that look off to me.
Gotta Have It mostly does their own authentication. They'll use Frank Caiazzo for Beatles sometimes, sometimes Roger. I don't care much for GA, but the MJ you posted looks like some major high-speed racker got to MJ.
