I almost overlooked adding this little gem, Billboard and Cows, which is currently hanging in my sun-room. It’s also an 18 x 18 piece, and although it is painted using a hard edge technique, you can see there is lots of texture. I guess we need a new term (see more below*.)
Also hanging in my sun-room are the two vertical pieces, called Shapes and Shadows 1 and 2. I think this view gives a more accurate impression of the colors, which came out a bit strong looking in the other photos posted. These two paintings work well side by side, I think — they were actually painted from the same source material — but they also work well on their own.
