If you ever wonder just how much the Tube Map is ingrained into British culture, then I think we have the answer here: drawn (and drawn well) by a six year old, complete with National Rail interchange icons. Fantastic!
This is my representation of the London Underground map (which I am very interested in) and shows the journey from my house to my Daddy’s work near Waterloo (identified by the star – which is unfortunately on the north side of the Thames!)
