Georgia O'Keeffe. Clam and Mussel, 1926. Oil on canvas, 9 x 7 inches. Georgia O'Keeffe Museum, Gift of The Georgia O'Keeffe Foundation. © Georgia O'Keeffe Museum. [2006.05.107]
In this small painting, a mussel shell rests inside a clam shell. The inner sides of both shells are visible to the viewer. The clam shell is light in color. Its hinge touches the left side of the canvas. The mussel shell is darker in color, and much of its visible inner side reflects its characteristic pearlesque luster.
