Series 1: Correspondence and Personal Material comprises the most voluminous series in Gillett Griffin's papers. Griffin was a prolific correspondent who often created several drafts of his letters and illustrated their salutations. Griffin filed correspondence in several different alphabetical runs. Some correspondence was also unfiled. The bulk of the letters were received by Griffin, but drafts or copies of his own letters are also present.

Gillett Good Griffin, a curator of Pre-Columbian collections at the Princeton University Art Museum from 1967 to 2005, spurred dynamic growth in the museum's collections of art of the ancient Americas. The Gillett G. Griffin Papers reflect Griffin's personal life and relationships as well as his professional work and his donation of objects to the Princeton University Art Museum.

Artwork includes primarily drawings and sketches. The series also contains some pastels and paintings, printing and printing plates, as well as childhood artwork, pieces from Griffin's studies at Yale, and book designs. The bulk of the drawings in this series are undated and unsigned, but many of the sketches appear to date from the 1990s and 2000s. Human figures are the most common theme. A great number of drawings were labeled "erotic" by Griffin and were often stored, as was much of his correspondence and artwork, in interoffice envelopes. Erotic drawings of men appear throughout the series, not only in the folders so labeled.
