There is no explanation for these. They stand on their own apart from the work illustrated. After looking through the catalog, I realize that Richard Tuttle's work is remarkable because it seems that you have never seen anything like it before. It leaves me feeling surprised and invigorated. Tuttle thinks of his work as drawing though there is usually a sculptural element in it.
Plywood is cut into an amorphous shape that looks something like an amoeba.
On the upper right corner is a perfectly round hole. A small, straight crack starts at the top of the hole and ends at the edge of the plywood. In the center of the plywood the artist painted an irregular oval in fuschia pink. On the lower right side of the oval is a small square piece of Styrofoam. Resting against the front of the plywood are two curving shapes cut from lauan.
