A very large folding map of the region with reference guide showing types and condition of roads. Meant for the English traveler. Also shows AA affiliates. Verso are 9 BW city plans drawn by John Bartholomew (Edinburgh) including Antwerp, Calais and Le Havre. Unfolding this while driving in the autos of the day must have been an experience...probably best to wait for a roadside café stop.
