Red Bird, 1964. Colored ink and pencil on paper, 12 in x 12 in. MoMa, NY.
“Red Bird is a drawing in pale red ink of only horizontal lines; so faint they register not much more strongly than the air stirred by a bird’s wing, although in her note on the museum’s acquisition form for this work Martin cautioned that it is “a bird in the mind, just by itself. A personal experience not about attributes”.
