This is the house that was the inspiration for my House on the Hill card in The Burning Serpent Oracle. It is the Spadena House built in a fairytale fantasy style by an art director for a movie director in 1921. since the 1934 it has been in Beverly Hills.
(From Rachel–The thing I love about this is that I suggested to Robert that it would be great if the house had a fairy tale quality about it. When he found the model he used, via Google Images, I agreed instantly that it was the perfect choice. Now, from the article–which he only just discovered, we can see how perfect it was.)
