Londons Underground

Londons Underground - After (Poster) One sheet vintage London Underground "Diagram of Lines," a landmark in information design originally created by Harry Beck. Map Details and History Designer: Harry Charles (H.C.) Beck, an electrical draftsman who revolutionized transit maps by replacing geographic accuracy with a schematic diagram using only 45- and 90-degree angles. Version: This specific version is the 1946–1947 edition (Diagram of Lines No. 1), notable for showing postwar expansion plans for the Central Line and Northern Line. Key Features: It uses two types of dotted lines to represent sections under construction and lines planned for electrification. Historical Significance: Beck's 1933 original design was initially rejected for being "too revolutionary" but became a global gold standard for subway maps.
