To mark their 40th anniversary, the Brewers have introduced an additional logo for the upcoming season.

The team will mark the occasion throughout the season with "Retro Weekends," which will salute a particular era in franchise history with throwback uniforms, bobblehead giveaways and appearances by former players.

The 40th anniversary logo blends the old "Barrelman" logo with the current "M" style. The logo will be worn on jersey sleeves this season and will be available for purchase beginning Jan. 31 at the Brewers On Deck event.

The Brewers were born in 1969 as the Seattle Pilots and, after a dismal performance during their inaugural season, relocated to Milwaukee just a few days prior to the 1970 season.
