I have Klimt's the kiss in my living room and a Nagel. I absolutely hate the Nagel because I think it looks like it belongs on the set of Miami Vice, but my husband likes it.
I agree with you aboutThe Kiss being too busy for the living room. I went out of town & my husband and father in law decided to surprise me by doing a "hanging". I now have very bizarrely hung pictures in my living room. One of these days I will re-arrange everything. I am also hoping to hang a male nude self-portrait of a friend of mine from uni. I love it; it reminds me of a cross between Scheile & Bacon (now THAT will shock the moral majority Americans - tee-hee naughty me!!!)
