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 his daily life on Coenties Slip.

In his journal entry for July 8, 1962, Indiana writes that Museum of Modern Art curator Campbell Wylly called, and came down for lunch. He reports that Wylly's trip to Washington, D.C. went well, and that to his "great good fortune" Wylly volunteered to help him retrieve wood from a warehouse. He notes that they "recovered two fine pieces of [the] Moon variety—one larger and one smaller" as well as an 1881 mineral water bottle, and goes on to say that Wylly "seemed to enjoy the physical expectations and fell uncomplainingly [to] the dirty work."

Indiana then records that the idea of going to a movie came up, but they couldn't decide on which, so instead rode the ferry to Staten Island and had dinner near the terminal. Upon returning he notes that Wylly helped him drag the lumber upstairs, and that he liked The Trilogy (The Melville Triptych).
