|This pump -- location no longer remembered -- shows an earlier
Phillips 66 logo, one that was phased out in the 1950s.
then it was a shield and a big "66" under the Phillips name.
The red, black and white shield with the large "66" in use today goes back to
late in that decade. It has been modified over time to add a controlled background
which embraces the fairly recent ConocoPhillips corporate name.
But the elements of the shield are very much as they have appeared for
well more than forty years now.
