Personally owned and used white porcelain tea cup belonging to legendary organized crime figure Meyer Lansky, featuring a thick gold gilt rim, burgundy base, gold-trimmed foot, and curved handle. The underside bears the painted maker's mark "RK" at the center and "Bohemia" in black at the base. In fine condition. Accompanied by a signed Certificate of Authenticity from Meyer Lansky's grandson, Gary Rapoport, affirming that the tea cup was personally owned and cherished by Meyer Lansky before descending through the family. The certificate is additionally signed by renowned historical experts John Reznikoff and Luke Pascal. Also included is a copy photograph depicting the Lansky family gathered around the dining table, with the family's silverware and table settings visible. Widely regarded as one of the principal architects of organized crime in America, Meyer Lansky helped establish the National Crime Syndicate alongside figures including Lucky Luciano, Bugsy Siegel, and Frank Costello. During World War II, Lansky also cooperated with the U.S. government through Operation Underworld, assisting naval intelligence in securing American ports against Axis sabotage. Personally owned household items belonging to Lansky seldom appear on the market, making this an exceptional artifact directly connected to one of the twentieth century's most influential underworld figures.
