Piccadilly Circus Tube Cutaway Diagrams

A challenge for you? Does anyone know where this great illustration from a children's book comes from? Magpie Moon found the book at a yard sale several years ago. She said: "I've been looking for information on where it came from ever since. I couldn't find a credit for it anywhere in the book and am curious to know whether there is a poster or larger print of it available."


I have a book written & illustrated by Laurence Menear called London's Underground Stations - A Social and Architectural Study and it features a number of cutaway diagrams including the one below of Piccadilly Circus


It's certainly interesting looking at the stations from this angle but the one from Magpie Moon's book is much lovelier in my opinion.

If anyone can help her identify the book or have any comments on these cutaway diagrams let us know. A number of people in the comments to the picture I uploaded would like to see more of these 3D models in station concourses.
