A golden-brown octopus spreads its eight sinuous arms outward from a rounded central body in this hand-colored scientific illustration, rendered with meticulous detail against a cream paper ground. The naturalistic study captures the creature's muscular form and delicate suction cups with the precision of 19th-century natural history documentation, creating a sense of both scientific accuracy and organic grace. 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.
