It has become clear that a number of pieces of art by Oldenburg contain the spoon motif, or a drawing, or even a model of Spoonbridge and Cherry. Since the line between rough sketches and works of art intended for display have blurred so much(the walker Art Center displays many of these drawings and models), and since I can not be certain that I can track down many of these works (especially those featuring the spoon motif) I have decided not to include these pieces in my official bibliography. After much consideration, it is sad to see them go, especially since they would enrich my bibliography so much.
