Great idea! I've bought pieces from galleries, storage containers, and artists direct and had this idea too. What art you buy says something about you. One thing is that art is a little bit like clothing- the brand matters. Something that is recognizable or has meaning outside of the visual work. Not sure if this is "legal" but if you can do art in the style of previous masters but custom to something that I like, I would buy that for sure. Or collaborate with living artists to create prints. Like a black swan portrait in the style of Juan Travieso.
