Secret Soviet Posters Demystify Map Symbols. These posters, part of a massive military program, illustrated how to map different types of buildings, bridges, and even trees in intricate detail.

Map symbols can include letters, coloured areas, pictures or lines. These symbols can be used to show the location of different features such as roads, viewpoints, bus stations, train stations ...

Of the 18 new symbols, six will replace existing symbols. A temple will be denoted by an image of a three-storey pagoda and police boxes will be symbolised by a saluting officer.
