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.

Indiana's journal entry for August 25, 1961, occupies two pages. At the top of the first page is a rough sketch of a dark moon, with the note "eclipse of [the] moon tonight." He writes that Art (clinical psychologist and art collector Arthur Carr) had not known that Indiana had assumed his visit the prior evening with a friend named Rod was a certainty. Instead they planned to come that evening, leading J. (Indiana's partner, fashion designer John Kloss) to rearrange his area in the loft, with Indiana following suit, making "an audio area in [the] front of [the] loft for radio and phonograph, redeploying constructions all over [the] place."

Indiana records that once Carr and Rod arrived they all went out for dinner and then returned home to watch the start of the eclipse from the roof, after which he "began negotiations for [his] summer survival."  He writes that Carr decided on a construction, advising him that "he had only a C[-note] to spend," which "spurred Rod [to] buy a small painting for a quarter." Both of these works are illustrated on the second page of the entry: the construction Slip, and a painting from June 19, 1961, titled Particci in Heat. Particci was Indiana's cat.

Indiana ends the entry with "Quadros resigns." He often referred to current events in his journals; this note refers to the resignation of the Brazilian president, Jânio Quadros.

The top half of the second page is Indiana's journal entry for July 26, 1961. However, he crossed out the text so that it cannot be read.
