December 26, 1926 His sketch of the actor Sacha Guitry was published in the New York Herald Tribune. Within two years, five New York newspapers, including the New York Times, were publishing his theatrical drawings. However, he continued to produce paintings, lithographs and political cartoons.

1945 To celebrate the birth of daughter Nina, he drew her name in the background of the theatrical drawing of that day for the play "Are You With It."
Continued to work Nina's name into his subsequent drawings; his readers would make a game of finding the Ninas. (In 1956, he began to append a numeral, following his signature,
indicating the number of Ninas in the drawing.)
"...[A]s the years progress, you see ...line simplify and the actual strokes elongate to where you actually become amazed at the complexity of that single, simple line. The mastery and beauty of that flowing trace of ink is regularly and stylistically contrasted with fine-line textures." (Unattributed quotation.)
