Michael Schneider Variety Editor at Large Pastrami-infused martinis, pink and white cookies and a “Maisel Tov” hot dog are on the menu as Amazon Prime Video has partnered with several different brands to help promote the final season of “The Marvelous Mrs. Maisel.” And it’s not just food partnerships. Companies ranging from Pantone to Saks Fifth Avenue are part of an ambitious marketing campaign tied to the April 14 premiere of “Maisel” Season 5. Activities that day include the series’ cast, along with exec producers Amy Sherman Palladino and Daniel Palladino, ringing the opening bell at the New York Stock Exchange, as well as a mile-long “takeover” of Fifth Avenue in New York from 46th Street to 56th Street and a 4 p.m. ‘60s-themed fitness class at the TWA Hotel at JFK airport.
