In 1958, President Eisenhower pronounced May 1 "Law Day," a thinly veiled (and strangely successful) effort to squelch American celebrations of International Workers' Day, which, in those days, fell on the wrong side of the Cold War. This linocut by the artist Frank Rowe entreats San Francisco's Yellow Cab to lift its ban on black drivers. "It’s one of the few political posters made during the Cold War 1950s," Cushing says. "This war veteran-artist lost his job as an instructor at a local college for failure to agree to a loyalty oath."
