In 1984, Don Mattingly hit .343 as a 23-year old and won the AL batting title, also leading the league in hits and doubles.
In 1985, Wade Boggs hit .368 (!), which got him the AL batting title that year. Only two players in the American League have hit higher than .368 since – Nomar Garciaparra in 2000 and Ichiro Suzuki in 2004.
In 1986, Fleer recognized that they both had spectacular mustaches, and made the baseball card you see above.
You see, there is value in the mustache.
