This coloured two-sided foldout map has a Postcode Map of London on one side of the sheet and an Administrative Boundaries Map of London on the reverse. The two maps cover the same area which extends from central London and beyond the M25 motorway to Chesham, Waltham Cross, Epping, Brentwood, Gravesend, Mereworth, Sevenoaks, Reigate, Guildford, Windsor and Beaconsfield. Main road mapping is featured as the base map, but there is no index to streets or places.
