A dense grid of vintage audio equipment, headphones, radios, boomboxes, and speakers fills the composition in intricate black line illustration. The monochromatic rendering captures the mechanical detail and tactile quality of analog technology from across decades, arranged in a tightly organized, almost taxonomic display that celebrates the nostalgia and craftsmanship of sound. 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.
