Garage Door, New Hampshire (for Robert Ryman), 2004.

I enjoy finding unintentional art, like this sloppily painted garage door. The first thing I thought of was the work of Robert Ryman, a painter who became known for his "white paintings," although he doesn't think about them as "white paintings." He is concerned with surface and truth to materials. 

“It was never an intention of mine to make white paintings. I don’t even consider that I paint white paintings. The white is just a means of exposing other elements. White enables other things to become visible.” 

(Ryman, quoted in Art News, Summer 1986)

For a good representation of his work, see the Dia: Beacon web site.
