Art, like property, has a lot to do with business, but even more to do with the buyer's taste. Perhaps the best way to insure your investment is by purchasing something you like. Art prices rise and fall, so if you buy something that you like, you'll be able to live with it through the lean years. Some basic knowledge in art is appreciated, but don't think that your knowledge begins and ends there. The art world is like any other market, it lives on what's happening today and it hunts for what will happen tomorrow, contemporary being the keyword.
