Thanks to DasWauto who really helped me out with dealing with Society6. I am really happy with the shirt, and for the price (17$ = 12€, no way I am getting a shirt for that kind of money over here) the quality is more then adequate.

It also should be mentioned that the artist, Cale Funderburk, was a pleasure to deal with. Check out his awesome designs, which include the '91 MP4/6 and a great Williams theme.
