How refreshing to have a piece of practical design that's so incredibly useful. No more creased scraggy maps where you suddenly find that the vital change between the Central Line and the Victoria line is buried beneath yesterday's lunch remains. Featuring the classic Henry Beck underground map (Zone 1 and its surroundings), the slick steel Pocket Tube Map, is the perfect credit-card sized guide about town. Londoners don't really like being seen glancing at the massive tube maps around town, we like to think we know the place like the back of hands, cool urban dwellers that we are - except that of course we don't know London like the back of our hands, considering there are 287 stations on the underground, so this cool and discrete little map is the perfect key to the city.
