The archives of the proto-Pop artist Larry Rivers, who died in 2002, will arrive at New York University in a few weeks, filled with correspondence and other documents that depict his relationships with artists like Willem de Kooning and Andy Warhol and writers like Frank O’Hara and John Ashbery.

But one part of the archive, which was purchased from the Larry Rivers Foundation for an undisclosed price, includes films and videos of his two adolescent daughters, naked or topless, being interviewed by their father about their developing breasts.

One daughter, who said she was pressured to participate, beginning when she was 11, is demanding that the material be removed from the archive and returned to her and her sister.
