I think the Keane pictures are charming enough-in moderation. Not as the exclusive genre in a home (and I know people who decorate that way. My aunt has a weird combo of Kinkaid and Eagle/military theme in her house. Disturbing!)
I was told about the Kinkaid pictures many many years ago-he didnt sell originals and I don't know that he ever claimed to. . . I went to a gallery around his death(there was one in my small hometown and I just wandered in) and they discussed the painting system with me. Even my aunt (who is generally kind of clueless about that kind of thing) knew (it was she who clued me in to ask the questions at the gallery). I like his stuff too-but it is way overpriced esp considering that no one gets anything original and now it is really overdone and cliched anyway. Too much popularity takes from the beauty in some sort of way.
I just get what I like, and if I pay too much, well at least I like it. I have no Keanes or Kinkaids. I buy the little artists showing at local fairs and galleries. I bought one thing on a cruise ship that while probably overpriced or not up to others standards, is absolutely something that makes me happy to see. So, I have a Dorit Levi reproduction of some kind. I love the subject, the colors and the feelings that it engenders in my soul. so there! My kids will probably sell it for $5 at my estate sale, but I have already got the value of it. (but I hope my daughter keeps it)
