Moscow's subway system turned 78-years-old last week. It started as 19 stations on one line; today it has 188 stations on 12 lines. As the system changed so have the maps, reflecting not only the growth of the subway system but evolving design trends as well.
Many of these maps can be found on a website run by Artemy Lebedev, founder of Art. Lebedev Studio. Lebedev's impressive online collection of Moscow Metro ephemera includes images, tickets, tokens, and maps (official and unofficial).
