It would be lovely to fill one's home with art work, but we don't all live the kind of life that allows for it. I have found that a way to feed my art passion is to buy art zines. Zines are usually homemade or small-batch produced books/booklets. They can be on any subject from DIY, to graphic novels, to feminism. I have been into zines for a long time and the ones that excite me the most are art ones or comics/graphic novels. I have bought quite a few over the years and they are usually very reasonable. If you're interested in buying an art zine or two, try Etsy, they have a zine section. Or look through the resources on the pin board below. Some of the ones listed on the board are actually free online graphic novels.
