A vintage neon sign glows in luminous green and cream script against a dark brick building facade, its elegant lettering spelling out "Green Mill Cocktail Lounge" in mid-century cursive. The photograph captures the sign's warm glow at night, framed by the building's textured masonry and industrial surroundings, evoking the nostalgic charm of classic Chicago nightlife. 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.
