"Dustpan" ?

Ok. Maybe my memory is a little foggy ? Maybe its one of those "faux" memories or somethin' ? Maybe its all that terrible beer I drank over the past few decades ? But, I seem to remember a commercial from the 1970's that showed a little old lady in the back seat of a Duster ... and she was always callin' the car a "Dustpan" ! Please help me out here ! Am I losin' it ... or what ??? LOL Tony
