*Core* is a commanding work by Richard Serra that harnesses the raw physicality of paintstick combined with the precision of screenprint on the full sheet of Arches Cover paper. Dense, gestural marks build an imposing presence, reflecting Serra's enduring engagement with weight, mass, and the psychological force of form. The interplay between the hand-worked paintstick and the mechanical screenprint process creates a tension that is central to Serra's exploration of materiality and spatial experience.
