I know this is a real collectors item I just don't know how much its worth but I suspect a lot.
fair condition stainless-steel business card:
At one point, after the demise of commodore, this company secured the rights to the Amiga Walker prototype (positioning themselves to become the new Commodore) and even employed legendary Commodore engineer Dave Haynie!
They were working on a revolutionary machine called the MMC and another prototype called the Torro. Not much is known about that machine except Torro is similar to the Spanish word for "bull" which conveys the connotation of power...
If any of these prototypes were ever made, I bet they still around and being used today based on the quality and durability of their business cards!
Cheers!
