This is an ad from 1962. It appeared, ironically, in LIFE magazine. It's for Humble Oil which later became Exxon Mobil. Here's what is says:
EACH DAY HUMBLE SUPPLIES ENOUGH ENERGY TO MELT 7 MILLION TONS OF GLACIER!
This giant glacier has remained unmelted for centuries. Yet, the petroleum energy Humble supplies- if converted into heat- could melt it at the rate of 80 tons each second! To meet the nation's growing needs for energy, Humble has applied science to nature's resources to become America's Leading Energy Company. Working wonders with oil through research, Humble provides energy in many forms- to help heat our homes, power our transportation, and to furnish industry with a great variety of versatile chemicals. Stop at a Humble station for new Enco Extra gasoline, and see why the "Happy Motoring" sign is the World's First Choice!
I don't know about you, but words can't begin to describe what I'm feeling right now after reading this ad, but I'm sure a lot of what I have to say to oil companies begin with F and end in UCKYOU.
