There are many benefits to buying original art.  Any keen observer can perceive the difference between a one of a kind work and something mass produced.  A hand picked original can bring a certain dynamic, filling a space with depth, feeling, and emotion.  It can "make the room".  Magic and inspiration are visible, even tactile, in high quality pieces.  Great works of art are essentially the evidence of the artist's expression, enlivening a space, and providing a daily inspiration for the viewer.
