Last year at the post East Austin Studio Tour follow up meeting an artist made the statement that when it came to marketing his art for EAST that he was just 'a dude and a dog' who lacked the resources to market his artwork. Even if you are just a Dude and a Dog (or like me, a Dude and Two Dogs) there is a lot you can do without a lot of resources.
Yahoo and Bing have similar local based sections. Your art is a local business and your studio is a local place of business. Google is the best of these since it not only allows your basic business info to be entered but also allows you to upload pictures of you, your artwork, a placement on Google maps, etc. You can also have your friends provide recommendations for your art, etc.
And best of all, if you are just a Dude and a Dog, it is all free.
