Bold black organic forms suggesting coral or seaweed clusters occupy the center of a soft beige composition, their biomorphic shapes overlapping and interlocking with fluid, gestural energy. "MATISSE" anchors the top in clean capitals, while publisher credits appear below, framing this work as a vintage exhibition poster celebrating modernist abstraction. Built from double-wall stainless steel and made to order, holding 20 ounces with a snap-on lid, a standard-cup-holder fit, and wraparound artwork. Your commute carrying original art instead of another branded tumbler.
