Bruce Nauman's *Studies for Holograms* (1970) is a portfolio of screenprints published by Castelli Graphics, New York, in a limited edition of 150, with each work individually signed, dated, and numbered by the artist in ink. The works reflect Nauman's characteristic investigation into the human body, language, and perception, using his own face as a subject manipulated through distortion and repetition. As numbered examples from the edition — including copies 48/150 and 95/150 — alongside a small run of artist's proofs, these prints represent a significant moment in Nauman's exploration of conceptual and process-based art.
