Harry Beck in his spare time. He was thus never actually paid for the map. Other sources report that he was paid a fee of five or ten guineas. In 1947, when he was not fully employed (having left London Transport) he began teaching typography and colour design at the London School of Printing and Kindred Trades. After long failing to acknowledge Beck's importance as the original designer of the Tube map, London Regional Transport finally created the Beck gallery at the London Transport Museum in the early 1990s, where his works are displayed. A commemorative plaque was installed at Finchley Central
Harry Beck given its first full publication in 1933 (700,000 copies). The positive reaction from customers proved it was a sound design, and a large reprint was required after only one month. It is suggested by Degani (2013) that one of the configuration techniques employed by Beck was that of an "underlying grid". In some cases the vertical and horizontal grid units are equalised, but on the whole the grid is rectilinear. The result is a "relaxed grid ... which has a certain rhythm and charm – somewhat similar to the grid used by modern artists (e.g. Piet Mondrian's painting "", 1937–42.)"
