This buy art stuff blog I wanted to go over themes. Some people like to keep it very classical by adding a little bit of gothic art to their art deco. Others favor the aztec art and use a spanish theme throughout most of their house. The only suggestion I can offer, is that you do not mix themes in one house. I know a few people that love art deco but do not know how to keep it seperate in its own theme. Having fairy art and aztec art hanging in the same room is trying to be too many things at one time. Pick one theme only and run with it.
