Closer Than We Think! Universal Language Boxes (1960)
The August 21, 1960 Chicago Tribune ran this Closer Than We Think! strip about "Universal Language Boxes" of the future.

A robot translating machine has already been developed by our Air Force. Right now it operates at only 40 words per minute and is bulky and complicated. But miniaturization, combined with magnetic tape, suggests far more dramatic possibilities for the future - a translating box that might listen to one vernacular and instantly relay a verbal translation. Any language would than be usable anywhere, universally!
