Bell System: Home is wherever there's a telephone

Bell System ad circa 1977~1978 in Spain.

Almost anywhere in the world you find yourself, you can find a phone. Then just tell the operator you want to place an international call, and you'll be back in touch with your family, friends, or business in no time—for less than you think. And phoning ahead when you plan your trip helps make it a smotth one, too. Long Distance is the next best thing to being there.
