I wouldn't buy a Kinkade painting as an investment. If you like it and want to enjoy it, that's fine. But I wouldn't count on being able to resell it for much. It might happen, but it's not terribly likely.
I think that it's fine to invest some (not close to all) money in a "hobby" rather than in something that's actually classified as an investment, but it should be an area that you really know. Art can be a good investment, but you're going to have the most luck if you're someone who reads magazines related to art, visits galleries regularly, studies individual artists, and so on. I just finished reading The Millionaire Next Door, and it recommends that as well.
