Wilson’s etched portrait of Martin Luther King, Jr. (2002) replicates a drawing he’d made some 20 years earlier. Shown here are the original drawing, the copper printing plate used to create the etching, and the print in 20 successive “states” or stages of development. Printed at regular intervals as Wilson and his collaborator, master printer Jim Stroud, augmented and refined the image on the copper plate, these trial proofs offer a unique glimpse into the artist’s working process.
