Here is a picture of the linemans Id wallet. It is embossed on the front with the Bell System logo and around it The Chesapeak & Potomac Telephone Co. American Telephone & Telegraph Co. My father saved these three cards but destroyed the other contents because they were licesnses and registrations for utility trucks etc. These three cards show that he was a life member of The Telephone Pioneers of America, was a retired employee of A.T&T andwas also a life member of the Communications Workers of America. I don't know who Donald L. Daugherty was but I commend and salute him for his service through the years. Take care to all.
