1949 Yankees stripe red
In 1949 the New York Yankees began an unparalleled run of five consecutive World Series championships. Their opponents were the Brooklyn Dodgers. The Yankees and Dodgers appeared in so many World Series in this era, unless a specific souvenir is dated or can be cross-referenced to another dated item, the exact year of issuance is speculative. In all likelihood some undated pins were re-issued over the years.
