There was a great article in the july/august issue of domino magazine, featuring more one-piece-of-art-a-day blogs and websites. News to me, but there seem to be many artists doing the same kind of thing that the fabulous site, a collage a day is up to. Wonderful art, created everyday, for sale, at reasonable prices. It's really cool to watch the process of an artist working through ideas and technique. I imagine the work might become less precious by doing it this way. Like exercising a muscle or practicing a skill.
There's a bit of a tension in purchasing art this way. When you find a piece you want, you have to bid fast to get it. Paying attention and acting quickly is key in this little corner of the art world. But it's definitely worth the effort. Who says you can't have wonderful, original art on a budget, while supporting an artist who is most probably on a budget themselves? And at this price, it's like DPK says: "get two, they're small".
Some of my favorite sites are:
