Look for art that feeds your soul, something more than decorative and disposable wall art. In my opinion there seems to be a lot currently on the market which looks quite nice but has neither conceptual depth or interest. This is problematic when collectors are looking to purchase art for long term investment.
My advice is to find an original artwork that you connect with both aesthetically and conceptually, this will guarantee you a long term appreciation and love for the piece. This doesn’t mean you must buy artworks which come deeply theorised by the artist and can only be unlocked by their artistic statement. Look for clues to help you interpret the work from its title, the medium used or the progress of the artist’s overall body of work.
The originality of art is one of its most precious qualities and my advice is to keep to a one-of-a-kind when investing in art. Prints and embellished prints are not originals and should not be considered in anyway original and most of décor art pieces are mass produced and the number of identical pieces is limitless.
