The Morgan Car Club Washington DC started its annual July MOG meetings in 1971. That was MOG 1. These continued without gaps until the COVID crisis came along.
 
MOG 7 therefore referred to the 1977 meeting. This was held in Luray, Virginia, where many of the early MOG events were held. The club had some very talented designers in their midst, one of whom was Robert Baker. He designed the lovely poster, featuring a flat rad Morgan 4/4, for this occasion.
 
Two unused copies of this poster have turned up. A rare find, for a poster that is almost 50 years old!
