David, Congratulations - another stunning London map - nobody does it better, in my opinion. The improved 'click to enlarge' feature is a real bonus. Best wishes for the New Year. Rod. In frozen Notting Hill, west London. Cross's London Guide 1851 displayed on the MAPCO website has been revised: Cross's London Guide 1851 http://london1851.com The thumbnail map and map images have been reworked to take full advantage of the wider format MAPCO website design. The 'click to enlarge' feature has been improved to give better access to very high quality enlarged images of each map section. This beautiful hand coloured map of London is printed on silk, and shows the site of the Great Exhibition of 1851 in Hyde Park. Of course 1851 was a significant census year, making this a map of particular interest to historians and genealogists.
