This idea comes from The Rap Sheet. Jeff drew attention to book covers over the years for particular titles so I decided to look at SERENADE by James Cain since my daughter had given it to me for Christmas. Mine was missing its cover but here are some of the ones I found. I think #2 is comical so I'd eliminate that one. Four doesn't have much flavor although the color combo is interesting. Six could be about western life, doesn't convey the noir aspect at all. Seven is too sixties. I vote for 1. There are probably more out there, too. What do you think?
