He said: "It's about London according to the blurb so I think it's supposed to look like a roundel (later edition has changed perhaps the lawyers thought it was too similar).
Patrick Macnee liked it - wondered what happened to him?"
Mark actually went to the trouble to get a better picture, than the one on Marilyn's site, for me when I said I was interested in blogging it, so he popped along to the British Library Barbican Library to get the book. Mark that rocks! (make sure you don't get a fine)
I'm guessing that the cover change is more to do with trying to make the book appeal to a particular target audience rather than worrying about its similarity to the roundel. If TfL's lawyers got their knickers into a twist about this "roundel" infringement, I think they would have way too much time on their hands.
BTW it's worth holding onto first editions or limited edition copies of books. I was at The Antiquarian Book Fair on Saturday and was amazed at how much books by authors, still well and truly alive, were selling for.
Take Neil Gaiman and Ruth Rendell, both are favourite authors of mine and have some written some brill Tube books in Neverwhere and King Solomon's Carpet, respectively. I'm sure I've got a pretty pristine copy of the first UK edition of God of Small Things knocking around which seems to already be worth $275 signed.
