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 page for June 25, 1962, Indiana discusses the demolition taking place on South Street, recording the he "heard strange, loud [and] uncomfortably close noises [this] morn'g, but did not discover their reason or origin until [he] went on [the] roof @ 1 for sun," and saw that the adjacent block in the rear was being razed. He also notes receving a letter from the artist Richard ("Dick") Smith, who mentioned that he spent the day with Ellsworth Kelly in London and that Kelly visited his studio. Smith also mentioned that Peter Cochrane of the gallery Arthur Tooth's & Sons (where Kelly's exhibition had just opened) had some photos of Indiana's work. 

The entry includes sketches of the sculptures Hub and Virgin, and a note next to Hub states "gesso in orbs btwn spokes." Indiana also records straightening the wheels on the sculpture Star.
