Baseball cap of the San Francisco Giants, 2010 World Series Champions. 39THIRTY model, one size. - Model Name: 2010 WORLD SERIES CHAMPIONS - Team Name: San Francisco Giants - Color: Primarily black Thank you for viewing. I received this as a souvenir from a friend who traveled to the United States in 2010. I have kept it in storage without wearing it. Although it is unused, I have listed it as "Like New" because I have home-cleaned it for the listing. This is a commemorative cap made when the San Francisco Giants of MLB (Major League Baseball) won the 2010 WORLD SERIES. It's made of sturdy material and has a cool design. Thank you.
