"The 70’s A’s grew mustaches because Charlie Finley had a mustache promotion night and he gave a bonus to any player that grew one as a tie-in to the promotion"

Yep. Rollie Fingers grew his distinctive moustache at the time and got the cash.

He still wears it that way.

Before the promotion, he was clean shaven, and it looks "odd" to see him that way.

Here he is. A rare look.

Please forgive the sizing.

I sat around talking with Rollie, Campy and other 70’s A’s a couple springs ago.

Rollie and Campy look good and Rolllie’s ‘stache is still there and well groomed.
