The Underground Logo

This (above) is the famous logo used by London Underground.  It is known as the roundel.  It is their trademark and is registered for their use only.  It was derived from the logo used by the London General Omnibus Company in the early 20th century when the red circle was a wooden spoked wheel and the blue bar was the word GENERAL.  A book about the logo has recently been published by Capital Transport Publishing called A Logo for London, ISBN 185414 232 1.

There is an on-line history of the roundel here:
