Artist Duane Keiser, who does the A Painting A Day blog sells beautiful little paintings, like this one of a marble, for $150. They're called oddments.
What's an oddment?Duane Keiser's Oddments
Oddment means "a remnant or part of something, typically leftover from a larger piece." I originally made these very small paintings on pieces of board leftover from my larger paintings. They are typically about 3"x2.5"
Unlike my Postcard Paintings, I post oddments on my blog without email notification. If you see an oddment available, email me at firstname.lastname@example.org and put the title of the painting you want in the subject line. The first person to email me gets it.
