Buy the Art that you fancy
The art piece may be an investment, but the basic rule of thumb is always to buy what you like.

Quote: “Chances are you are going to be living with these objects or images for quite some time, so you want to feel comfortable about having them around your home or office. ”

It may also be vise investment wise, since if you want to get any money out of it somebody else has to buy it eventually. Chances are that if you like it - so will others also like it.
