Robert Indiana kept a series of illustrated journals during the late 1950s and 1960s, in which he discusses the development of his work as well as daily life on Coenties Slip.
Indiana begins this journal page, dated April 10, 1962, by noting that he received a collage from the artist Ray Johnson in the mail that morning. He also records a visit to the artist Lenore Tawney to pick up money to pay an overdue light bill, and a call from the curator Campbell Wylly of the Museum of Modern Art, who had recently dined with the Duchamps [artist Marcel and his wife Alexina] and Staempflis [gallery owner George and his wife Emily].
He discusses returning to work on the constructions Four and Jeanne d'Arc, and includes sketches of a detail of both works. Below the sketch of Four he notes that the "4" and "FOUR" become black from the white they were yesterday, and below the sketch for Jeanne d'Arc he notes making the "J" that was a pencil stencil outline a cadmium red letter.
