NEW YORK (AP) — The estate of Roy Lichtenstein has donated 21 of the pop artist's sketchbooks and two of his early drawings to the Morgan Library & Museum.
The New York City museum said Friday the works were a gift from Lichtenstein's wife, Dorothy.
Lichtenstein died in 1997.
The museum says the sketchbooks provide valuable insight into Lichtenstein's method and subjects.
It also is receiving 11 of the artist's remaining sketchbooks from the Roy Lichtenstein Foundation on long-term loan.
Dorothy Lichtenstein also donated several original drawings by other artists from Lichtenstein's personal collection. They include works by Andy Warhol, Brice Marden and Robert Rauschenberg.
The drawings and some of the sketchbooks will be included in an exhibition at the Morgan in February.
The museum presented an exhibition of Lichtenstein's drawings in 2010.
