Concentrate While Telephoning (1917)


"The 1917 Chesapeake and Potomac Telephone Company publication "How to Use the Telephone, 1917" is a clear, sensible guide to managing your "delicately adjusted instrument," including useful tips like finishing your calls with "good-bye" so that the other party doesn't suppose that the operator has cut them off."
Funny :-))) via boingboing.
