For those interested in books and things that make nice references to K-F or Willys products, I suggest you try to find BOULEVARD PHOTOGRAPHIC. It's the story of one of Detroit's most innovative outside photography firms doing work for the magazine ads, brochures, special items, etc. used by the auto industry from the mid 1950's and onwards. There's an interesting back story on a photoshoot of the 1952 Willys Aero Wing and the Kaiser-Darrin Sports car in 1954.
