Well like I said I'm being a jerk with this book and so far I'm only up to France and I have found two incorrectly identified aircraft, however on the plus side I have not seen any of these photos before that I can remember. Even if it only came with what I have seen so far it would still be pretty much worth it, around $20.00 US more or less. Another plus is the balance of the correct captions are much more extensive, in most cases, than in previous books by the author. All in all I am very happy with it.
