"SP" is a series of twelve screenprints by Josef Albers, each meticulously signed, titled, and numbered in pencil, reflecting the artist's characteristic precision and systematic approach to art-making. Published by Editions Domberger, Stuttgart, for Galerie der Spiegel, Cologne, the suite was produced in a limited edition of 125, underscoring its collectible nature. The sequential titling from "SP I" through "SP XII" suggests a deliberate exploration of a central visual concept across the series, consistent with Albers' lifelong investigation into color relationships and geometric form.
