Remember These?
 

Johnny Miller Men's Wear
Jack Nicklaus line by Hart, Schaffner & Marx
Bobby Clampett shoes--spikeless w/ big knobs
Paul Hahn Jr. commercials for Etonic shoes
Laura Baugh toothpaste ads
Eddie Pierce shoe commercials
Ken Venturi golf shirts
Gary Player Sportswear

Any others? Can you go back further?

Penguins
 

How about those Munsingwear shirts witht the Penguin logo. It's a great retro look now, but the shirts are tough to find and go for 60 to 80 bucks.

I still remember seeing a Paul Hahn trick shot show in upstate NY when I was about 10. Probably 40 to 50 people in attendance. He had pretty good action and I can recall playing well that afternoon just from mimicking his move.

The King...
 

...puffing on (and endorsing) L&M cigarettes.

Nicklaus doing tv ads for Uniden "wireless" telephones....

Watson doing "My Broker is E. F. Hutton..." commercials.
