The full image is in the link here, and should keep you busy for a while! Many thanks to @NewburyNewbie (who originally found this on News of the Unreal) for sending this my way.

"The magic, mystery & sometimes maddening shortcomings of London's Tube are documented with love, enthusiasm & sometimes despair by its unofficial social historian." The Guardian
