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 activities.

In his journal entry for November 17, 1962, Indiana records taking a new brace he had made for the "Dream" (The Red Diamond American Dream #3) up to Stable Gallery, and once there having breakfast and then putting the painting together, the "new device working beautifully." He then describes a visit to the gallery by collector Leon A. Mnuchin, who came in as Indiana was on the floor signing The Calumet. He writes that they were introduced by Alan Groh (the gallery's director), and that Mnuchin wanted to see the painting again (which was acquired for the Rose Art Museum, Waltham, Massachusetts with the Gevirtz-Mnuchin Purchase Fund), and was "still pleased with his purchase." He also notes that Eleanor Ward came to the gallery later, but that they had little time to talk, and that he had to return back to the studio without seeing Campbell Wylly's drawing show (at the Museum of Modern Art's Penthouse and which included a drawing of Indiana's). 

Indiana writes that he was able to rest, and after dinner decided to go to Marge Turon's party, where he walked in "to find Martha Jackson, Tibor de Nagy and John Myers in serious conversation in [the] front room," and did not intrude on them or receive a greeting. He notes that he learned from a new worker at Jackson's gallery that she had his work Comma in her collection, as he had thought. He also records that Jane Wilson was one of the few painters there, that he had his first conversation with her, and that her husband, John Gruen, had just been appointed the arts critic at the New York Herald Tribune.
