A rotary telephone dial from 1957 dominates this black and white photograph, its numbered finger holes and letter combinations arranged in a circle around a central "PUBLIC TELEPHONE" hub. The grainy, high-contrast image captures the mechanical precision of mid-century communication technology, with partial views of the phone's outer casing visible at the edges, creating a nostalgic document of analog-era artwork. 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.
