I love, love, love this 6 x 12 size. The panels are kind of hard to find, so I actually have a backlog of 5 or 6 paintings I'd like to do at this size, as soon as I can get more.
Meanwhile–here's one of them. New York City, of course. This is down by NYU on a rainy afternoon.
6 x 12, oil on 3/8 inch cavnas-textured fiberboard with slots in the back for hanging. Click here to bid, and go here to see more paintings. You can also see a full gallery of paintings on DailyPaintworks.
