Which book??

Went to Lancaster, and took a break from shooting and went into waterstones to look at there photography books, after looking through some amazing books, which included work from Capa, HCB, Ansel Adams etc i felt incredibly inspired. I noticed a man at one of the book shelves, looking through the books and seeming couldn't decide which one to use. I composed my shot, focused and fired the shutter, the speed was about 1/8th of a second at f2, the huge advantage of rangefinders is no mirror shake, with a slr this shot would have been very difficult to get handhold. I was using my Kiev 4 with jupiter 8. Also the quite shutter of rangefinders was advantageous in this situation as the man was non the wiser that id taken his photo.
