The wording on Libby Tucker's calling-card read: "Sunset Valet Parking. No party is too big or too small" and on the other side, "Libby Tucker, New York, Trained Actress. No part is too big or too small".
In the closing scenes Libby is first seen sitting on the left side of the bus talking to her seat mate, then when Herb drives his car up next to the bus on the right side she sees him through the right side window.
