The jerseys are replicas of the uniforms worn by the two teams the last time they met in Boston, in 1918. The Red Sox have at least one high-profile staffer who is not a fan of them.

"Not good," manager Terry Francona told the Globe's Peter Abraham.

The Red Sox wore plain white uniforms and caps for most of the 1910s and 1920s, according to the team, and didn't add words to the front until the 1930s. The Cubs, on the other hand, changed their uniforms almost every year in the 1910s.

The uniforms will be signed by the players and auctioned. Proceeds will go to the Red Sox Foundation charity.
