She generously responds to an autograph request by including a sketch of a young woman on a subway train.
Bishop writes, "Thank you for your note, telling me of your being an autograph collector. You honor me by including me in your list...." To the left of her closing and signature, with pen and ink she draws a pensive, or perhaps napping, young woman on a subway, eyes closed, face resting on her hand. She sketched a question mark above her hair and noted the address for Times Square on the car's back wall, "42 St." She signs in full, "Isabel Bishop."
Bishop studied in New York at the Arts Students League and made New York her home. Her painting and illustration focused on the city's people and landscape particularly after she moved to Union Square in 1926. Before arriving in New York City, Bishop painted nudes in a realistic style.
