San Francisco is the home base of a car club which caters for all kinds of British cars, the North Bay British Car Club, for shirt NOBBC.
Ten years ago, in 2014, this club issued a small series of car badges, designed by Tcherek Kamstra, who also designed a good number of Morgan badges. 
Of course, the badge featured the Golden Gate bridge, behind a red Morgan and a blue Jaguar XK 120.
Two examples of this badge have turned up, still as new.
A great badge to have!
