MILWAUKEE -- The Brewers are expanding the Retro Friday promotion to "Retro Weekends" in 2010, part of a year-long campaign to commemorate their 40th anniversary season.

The team will host four Retro Weekends, one for each decade of Brewers baseball. On the first three Fridays, Brewers players will wear retro uniforms from each era, and on all four Sundays, the team will give away a bobblehead doll representing a great moment in the club's history.

Along the way, Brewers players will wear special 40th anniversary season patches throughout the season and Brewers fans will have the opportunity to vote for the best moments in team history in a "40 Years/40 Moments" campaign being coordinated in partnership with FOX Sports Wisconsin, Brewers.com and the team's flagship radio station.

More information about the voting program will be announced in April. For now, the team released details for the four Retro Weekends:
