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
Commemorative plaque plaque scheme run by English Heritage in London, although these were originally erected in a variety of shapes and colors. The National Trust (which is a non-profit charity organization unlike English Heritage and English Heritage properties) has its own similar markers as well. However, not all historical markers in the United Kingdom are blue, and many are not ceramic. There are commemorative plaque schemes in Bath, Edinburgh, Brighton, Liverpool, Loughton, and elsewhere—some of which differ from the familiar blue plaque. A scheme in Manchester uses color-coded plaques to commemorate figures, with each of the colors corresponding to the person's occupation.
