Despite the complexity of making the map, Beck was paid just ten guineas for the artwork and design of the card edition (five guineas for the poster). After its initial success, he continued to design the Tube map until 1960, a single (and unpopular) 1939 edition by Hans Scheger being the only exception. Meanwhile, as well as accommodating new lines and stations, Beck continually altered the design, such as changing the interchange symbol from a diamond to a circle and altering the line colours of the Central line from orange to red and of the Bakerloo line from red to brown. Beck's final design, in 1960, bears a strong resemblance to the current map. Beck lived in Finchley, North London, and one of his maps is still preserved on the southbound platform at Finchley Central station, on the Northern line. In 1997, Beck's importance was posthumously recognised, and as of 2022, this statement is printed on every Tube map: "This diagram is an evolution of the original design conceived in 1931 by Harry Beck". After Beck By 1960, Beck had fallen out with the Underground's publicity officer, Harold Hutchison, who was not a designer himself but drafted his own version of the Tube map that year. It removed the smoothed corners of Beck's design and created some highly cramped areas (most notably around Liverpool Street station), and the lines were generally less straight. However, Hutchison also introduced interchange symbols (circles for Underground-only, squares for connections with British Rail main line services) that were black and allowed multiple lines through them, as opposed to Beck, who used one circle for each line at an interchange, coloured according to the corresponding line. In 1964, the design of the map was taken over by Paul Garbutt, who, like Beck, had produced a map in his spare time because of his dislike of the Hutchison design. Garbutt's map restored curves and bends to the diagram but retained Hutchison's black interchange circles, although squares were replaced with circles with a dot inside. Garbutt continued to produce Underground maps for at least another 20 years. Tube maps stopped bearing their designer's name in 1986, when the elements of the map then had a very strong resemblance to today's map. While the standard Tube map avoided representing most mainline services, a new variant of the map issued in 1973, the "London's Railways" map, was the first to
