In 1933, when Henry Beck designed a new map for the London Underground, little did he know that it would be printed over half a billion times – more than any other map in history. Many consider it to be a schematic map where the need to display location based information in a simplified and clear form has succeeded over geographic realities. Train stations are shown equal distance apart and London is not as large as it seems. Whether it can be described as a map I will leave to others, but it continues to inspire others by its clarity and aesthetic beauty. Click here for a great article on Henry Beck and his London Tube.
