Painting a Day blogs have been the subject of more than a few articles recently. Touted as a cheap "in" to purchasing original art, the blogs feature postcard sized paintings done in one sitting (1 - 3 hours in most cases). The subjects range from simple household items to outdoor scenes, most accompanied by the artist's description of their inspiration. Many of the paintings are quite stunning, like this egg by Duane Keiser. Keiser's works are available for sale on e-bay and sell for $100 and up.
