1966 Phillips 66 Gasoline Magazine Ad - Go First Class #600

This original 10 x 13" Phillips 66 Gasoline magazine ad from the sixties is undated, but based on the car and other ads that I have from this magazine it is most likely 1966.  The ad features a blurred rear end of a period automobile racing away from the camera to promote the power the gasoline brand delivers to your engine.  Ad is in nice used condition.
