Investing in Art can be a lucrative activity if done properly. The first objective when selecting your investment is to make sure that the piece(s) are authentic. If you are commissioning a living artist to create a specific piece, you will want to have it delivered with provenance that certifies authenticity. When you go to insure the piece(s) and if/when you engage in the transfer of ownership, you will be required to show that the Art is genuine.
Types of Art to invest in should be gauged in aesthetics if you plan on using said pieces for personal decorative display. If you plan on having the works make the rounds for public consumption which can often be a beneficial write-off, personal taste is obviously less of a concern.
As you can see, specifically commissioned pieces are a great way to enjoy a collection and make a perfect addition to compliment any vintage or historic works that you have invested in.
