I just did a 1950s kitchen for a client and am doing an Art Deco style Bedroom as I write. P.M. me if I can help with anything. An idea that I always use is very wise thing, I feel, is first invest (or in my case, look at, as I already have a few) in some home decorating magazines from that era.
What I look at is, Better Homes, The American Home or Sunset (a big list, but you get the reasoning) for some great ideas. Good Luck!
