Classic Cars New Hampshire USA Traffic Park Award Postcard

MG This undated but modern origin real photo postcard and I believe an award winner when taken in 1976 shows an aerial view of cards all parked together at Manchester New Hampshire from a view high from the skies - but when you look down this is a further assault on the senses as the image is almost a face how it has been created (the two cars the eyes - the middle cars the nose etc... and if you look again you will see all the lines around the cars are almost like a scalextric track or railway but they are in fact just debris enhanced - this  is unique for any automobile collector of rare postcards which reverse has the photographer and its photos date location identification etc which is unused and pristine condition
