Bear in mind you won't get this book in time for Xmas if you order through amazon.co.uk (these guys look as though they can deliver faster in this instance). However, as I'd been mentioning Mark Ovenden so much today, I wanted to give some notice to his co-speaker Max Roberts who gave us a fascinating look at how guide books around the world have their own interpretation of the London Underground map, when they are too tight to pay the rights for the real one.
Max says "I am particularly keen to hear about unofficial London Underground maps, both from Britain and from around the world. I already have over 50 in my collection, mainly from Japan, France, Germany, and USA, and mainly from the last 5 years. Complete maps are the most interesting, and any unofficial maps from before 1990."
However, Max's book "picks up where Ken Garland completed his work (Mr Beck's Underground Map) to take the story of the map from when original designer Henry Beck's services were dispensed with for good, to the present day. Based upon extensive research of London Transport archives and at the London Transport Museum, this book surveys the major changes that have taken place to the map over the years, and the reasoning and political background that led to them."
