The Moscow Metro opened for passengers in May 1935. From the outset, its emblem was not standardized and over the years was repeatedly subjected to spontaneous and uncontrolled transformations: it changed its shape and proportions, acquired contrasting contours and a tunnel-shaped outline, lost serifs and was illuminated by neon. Only one thing remained constant: the Moscow Metro was always symbolized by the red letter M.
A large-scale research of the history and development of the Moscow Metro logo was carried out in the studio in order to understand what the famous letter should look like today.
