A book providing a detailed explanation of Leica's history and models. I've only read it once. It's in good condition, but as it's been stored at home, please consider purchasing only if you understand that it's a used item. - Title: Leica Story - Author: Kazuhiro Nakagawa - Contents: Leica's History, Leica Lenses, M-series Leica, etc. Thank you for looking.
