This series contains items pertaining to Antonucci's personal life, as well as his teaching, from the 1950s until his death in 2006. Though primarily working as a freelance designer for most of his life and career, Antonucci also held several part-time positions at Parsons School of Design, even drafting ideas regarding program and curriculum design. The teaching materials included here reflect this engagement via correspondence, notes, and drafts of curricula.

Also included herein are materials documenting Antonucci's relationship with the family of couple Ruth Cullen and Joe Sarnelle. Ruth, Joe, and their children were close friends with Antonucci throughout his adult life. This series contains birthday and holiday cards, correspondence, wedding and birth announcements, and photographs of Ruth and Joe and their children, D'Arcy and Cullen. Some of Ruth's poetry and other writings can also be found here. In the nineties, Antonucci developed a working relationship with Ruth, and the two of them illustrated and wrote, respectively, a series of children's books published on the Paulist Press. Items relating to these books are found in the design projects series.
