New Super Detailed Motorist's Map, Sheet 7, Herts & Essex
Radically different style of cover, with printed sketch map of area covered and title, with the scale (3 Miles to the Inch) very prominent. No price on the cover. Back cover has adverts for 27 sheets of thge Great Britain 3 Miles to 1 Inch maps (this being sheet 7).
The map goes further north and west than on the earlier 3 Mile maps, and hence also a change of name - to Herts & Essex. No county edge-borders.
Motorways are in blue, Primary Routes (class A or B roads) in green, class 1 (A) roads are in red and class 2 (B) roads are in yellow.
Scale correct at 25 miles = 210mm, or 3.0 miles/inch, ie 1:190,000.
