I am in search of an ad that ran in Playboy, Penthouse or another magazine in the 70's.?

The picture in the ad had a man (I think in a bathing suit) and a woman with long straight brown hair (maybe in short-shorts?) in it on a beach. The woman was kneeling and holding a bottle of beer (maybe Michelob?) She was topless and very small chested. I am not sure if the ad was for Playboy (what kind of man reads Playboy i.e.) or for beer or what. It made an impression on me when I was young. I would love to find a copy online. Thanks.

You remember that ad from that long ago? Wow, you really know your porn, don't you?
