121: Vertical Diptych 2 Artistic Silke Grossmann 1980
Vertical diptych— arrangement of two prints, intended to be mounted one above the other. The upper print is 9 ¼" x 14", the lower 10" x 15", both on 18" x 24" paper. Stamped, and signed and dated in pencil on verso.
Aside from the compositional vitality of each print, the juxtaposition creates a curious sense of movement (as the diagonal shadows go in the opposite direction, so more has moved than the woman's body.)
