A commanding large-format lithograph by Richard Diebenkorn featuring his signature interplay of geometric forms rendered in stark black and silvery grey. The composition presents a perspective-defying interior space — a luminous central square receding into a dark surround — characteristic of Diebenkorn's mature abstract vocabulary. Published by Gemini G.E.L., one of the most prestigious print workshops in America, this edition of only 42 examples is among his most collectible graphic works. The pristine condition and signed status make this an exceptional opportunity to acquire a museum-quality work on paper.
