Speak Closely Into the Transmitter....

From the 1913 Neenah-Menasha telephone directory

Even as a boy in the '60s, I recall Ma Bell still publishing public service-type ads in the phone book, reminding us how to dial the phone properly by allowing the dial to fully finish rotating before dialing the next number, speaking clearly, looking up the correct number first to avoid misdialing, etc. 

Remember when we had 5 digit phone numbers and that letter prefix?  My phone number was PArkway 2-6579 and we had a party line.  Explain that to your kids today. 

Let's all take the "telephone pledge" now....
