Here is a commercial for sugar-free Tab, a diet cola. The commercial, which appears to be from the late '60s, early '70s, is part of Tab's "Be a Mindsticker" ad campaign.

Shows a rugged-looking man in a suit juxtaposed and superimposed over shots of a woman walking in nature. Eventually, the woman arrives at a picnic. She lays on blanket next to her food and a six-pack of Tab, cheerful and ready to start consuming things all by her lonesome.
