The Morgan Sports Car Club Lincolnshire Centre -better known as LIN MOG-  has issued several versions of the badge featuring the small yellow monster.
 
The earliest is one with the light green bottom, numbered on the rear. These are now hard to find in nice condition. Later ones had either a dark blue, dark green or sand coloured bottom. 
 
Of the light green bottom version one copy is available, of the sand coloured bottom version two copies. These are numbered on the rear and date from the 1990s.  All are excellent.
