If your a big Leica fan the Leica Museum book by Lars Netopil is a must have addition to your library.
There are only 2 negatives that I have to say about the books. First, from a commercial photographers view I wish the shadows had been filled in. Sometimes the light falls off to abruptly. Second, there are a lot of white marks on the pages from paper dust in the printing process. But don’t let these flaws keep you away from these 2 books. There is a lot of information packed into these 2 volumes.
