Just ordered 'Auto Union Album 1934-1939' from Classic Motor books (www.motorbooks.com or 1-800-826-6600). This is a new book by Chris Nixon who also wrote 'Racing the Silver Arrows- Mercedes vs Auto Union' which is back in print and a very good book if I say so myself ( also can order from Classic Motor Books). If you saw the 24 hours of Le Mans profile of The Audi team and Auto Union's racing history (speed Vison) then you know the first image seen was a TT front end. So get in touch with the history of the mark; these books are not cheap ($80.00) but I highly recomend them. JIM
