The marquee outside Wrigley Field in Chicago was painted green and gold Wednesday to match the colors from the 1930s as part of the field's anniversary celebration, before the Cubs' home stand against the Milwaukee Brewers and the New York Yankees beginning Friday.
On Saturday,the Cubs will wear the uniform from 1937, the first season the team wore royal blue. The Milwaukee Brewers plan to wear throwback uniforms of their own that day.
The team says fans will notice other sights and sounds from the 1930s, too.
Wrigley Field opened in 1914 and is being celebrated this season.
