A real classic!
 
The badge for the 35th anniversary of the Morgan +8, issued by the Morgan Sports Car Club Holland, designed by Geoff van Beek. The title 3.5 decennia refers to both the 3.5 litre Rover V8 engine, and the 3.5 decades the model had lasted.
 
As the badge is a virtually perfect copy of the 15" +8 rim, it is also known as the "wheel badge" :-) 
 
Only 80 copies of this badge were made.
