Alexander Calder 'Vertical Flags' Artist's Proof Lithograph

This item is an original color lithograph by the American kinetic sculptor and artist Alexander Calder (1898-1976), titled 'Vertical Flags'. The work is an Artist’s Proof (designated by the notation 'A.P.' or 'E.A.') and features Calder's primary signature in pencil at the bottom right. The composition is executed in Calder’s signature mid-century modern abstract style, characterized by bold primary colors—red, yellow, and blue—alongside heavy black linear forms and organic shapes against a cream-to-white paper background. The artwork features two distinct vertical arrangements: a left-side scrolling vine-like motif with black, red, and yellow 'petals' and a right-side geometric central axis with alternating red triangles and adjacent circular forms. The construction appears to be high-quality lithographic ink on thick, archival-style paper. The piece is housed in a contemporary thin-profile metal frame with a matted border. Estimated to be from the mid-1970s, the piece shows no significant foxing or water damage, though light paper toning and minor frame scuffs are visible, consistent with age. The craftsmanship reflects Calder's kinetic philosophy, utilizing static shapes to imply movement and balance through vibrant color blocks and confident line work.
