I agree with everything you just stated
@anotherbob: When it comes to artwork, I found a genre that I enjoy and I have several paintings each from several artists, now dead, whose art work is still affordable but is slowly being "rediscovered".
For me, since I can't purchase a Monet or a Van Gogh, I have found that I can in fact purchase paintings of high quality that seem to have that certain "something" but at an affordable price.
Not everyone who slabs a canvas with paint demonstrates that quality, but just like seeing a Van Gogh up close - you know it when you see it.
I obviously won't name the artists whom I am interested in because there are several works I am still interested in obtaining and I just haven't gotten to the point to make an offer on those works.
Find a theme or genre that resonates with you. Research the artists who painted in that genre and after awhile, you will see certain names repeat over and over, Then, start examine their works as well as the ones that are up for sale.
I predict you will find yourself a happy person and someone who has a well decorated home.
You may not have propped them up while the artists were living, but you will ensure that their contributions are not forgotten.
Investment is secondary, but with luck, you might see some increased value as well.
