Woolworths Vigilant Ad from 1968
Here is a copy of the earliest known archived ad on the Vigilant Burglar Alarm. The ad was run by Woolworths in the Milwaukee Journal on April 22, 1968. The simple alarm featured a pull string that you would attach to your door, and when you opened the door the string would pull the pin and activate the alarm. We have one of the original alarms from that era displayed at our corporate office.
