San Francisco Giants I Feel Good Pin - Circa 1980's - Excellent Condition

This is a vintage San Francisco Giants "I Feel Good" button/pin from 1989. The SF Giants were giddy going into the season. They had an aligned management structure and a fun ball club with a Humm Baby attitude led by Roger Craig and players with a super gung-ho attitude out of players like Will Clark. It was the year the Giants went to the World Series and it was also the infamous Bay Bridge Series and the infamous Game 3 Earthquake Loma Prieta Earthquake. The button/pin features white background with orange, and black writing with an attached straight pin fastening mechanism. Measures 2” in diameter
