For the May 7, 1965 issue of the Johns Hopkins University student-run newspaper "The News-Letter", senior William (Bill) Katz wrote a brief article on three Robert Indiana posters that were hanging in the newly built Eisenhower Library. Praising Indiana’s work, Katz wrote, “Numbers, words, and geometrical shapes evolve in Indiana’s work to reveal lasting and evocative images.” Katz’s words readily apply to this print, which announced the date of his commencement on June 5, 1965. (Katz dedicated this impression on the reverse to Gertrude Rosenthal, then Chief Curator at The Baltimore Museum of Art.) As Indiana’s friend and studio assistant, Katz guided the artist’s work on several collaborative projects, including the publication "Numbers" in this case.
