Art is used for investment and tax purposes. All that matters is that it is rare, verifiable, and created by someone famous (at least in the art community). The actual art can be pure crap. It doesn’t matter.
A while back I read an article about how to make money off art and photography.
Basically it said to hang around gay people and photograph them doing gay things and then show it off to liberals so they will get your name out there.
My attitude is to do what I like and if others like it too, they’ll pay for it.
