The art on this 1962 Vintage New York Mets Sweatshirt has been custom produced by Vintage Brand. In 1957, the Brooklyn Dodgers and New York Giants relocated from New York to California, leaving the largest city in the United States with no National League franchise. The history of the New York Mets began in 1962 when the team was introduced as part of the National League's first expansion of the 20th century. The team's history includes two World Series championships and five National League pennants. The Mets took the field for the first time on April 11, 1962 against the St. Louis Cardinals.
