The Sea No. 2 from Outer Sand Island (1939) depicts waves crashing onshore, a scene typical of the uninhabited islands found along Maine's coastline near John Marin's Cape Split home, which fascinated the artist throughout his career. Showcasing the rocky shores and sandy beaches that were a recurring motif in his work, this watercolor also illustrates Marin's constant exploration of various framing techniques and methods. Presented with a reflective metal mat, a red paper inner frame, and a natural wooden outer frame, this piece highlights Marin's tendency to experiment with his framing and compositional styles. Throughout his long career, the concept of the frame became one of Marin's primary motifs, featuring a range of avant-garde forms, methods, and styles.
