I just received "Sportcar Racing 1962-1973" by Rainer Schlegelmilch, a legend of motor racing photography. The book is dripping with photos of drivers wearing various watches, I've spent a couple of minutes flicking through it and already spotted Autavias, Carreras and a few Rolexes. I'm in England and from Amazon the hardback cost me £24 with free delivery. It has about 540 pages, is hardback in landscape format, the paper quality is matte and very good considering price and number of pages and I have absolutely no connection to the publisher or anyone else involved!

I also received another book, "Racing Demons - Porsche And The Targa Florio" by Michael Keyser ("Speed Demons" and "A French Kiss With Death"), Mark Koense and Enzo Manzo. I haven't had a chance to have a look at it but it's huge and comprehensive:

Just sayin'!
