In the Ricardo’s Hollywood apartment where they stay while Ricky is making a movie, we see a Georges Rouault framed print on the wall.
See it on eBay

Georges Rouault 1871 –1958 painted in a style associated with  Fauvism and Expressionism and was popular with mid-century collectors. His works reflect his background as a stained glass artist. Rouault  burned 300 of his pictures a while before he died because he felt he dd not have time to complete them.
