Robert Motherwell's *London Series I* is a suite of lithographs that exemplifies the artist's mastery of bold, gestural abstraction, characterized by his signature interplay of stark contrasts and expressive mark-making. Published by Marlborough Graphics, Inc., New York, in an edition of 150 with 10 artist's proofs, the works reflect Motherwell's deeply personal visual language rooted in Abstract Expressionism. The varied designations across the prints — numbered editions, artist's proofs, and a unique proof — highlight the intimate relationship between the artist and the printmaking process.
