Not trying to be offensive, but you would have to be blind to believe that THAT picture of the business card is real.
In THAT picture there are clearly a number of defects, including:
The shine on the boing ball, does not fit with the lack of shine on the rest of the card.
The AA on the Amiga logo does not fit with the crisp reproduction of the rest of the text.
As far as I can tell, THAT photo is a fake.
Now if there are other photos, they may prove otherwise but all the evidence on that one is damning!!
