That’s correct. Both National League teams left, then a few years later the New York Metropolitans Baseball Club was formed. Used the Giants’ NY logo, and Giants’ orange and Dodger blue as the colors, coincidentally two of the colors of the New York Ciy flagI’ve always been of the impression that the Mets were created by the vacuum left by the NY baseball Giants and the Brooklyn Dodgers leaving for California. Just look up the logo for the Giants and add Dodger blue and you have the Mets logo. So 3 teams then 1 team to finally 2 teams.
