Walt, you are right that the ART cars would most likely have been changed
to the paint scheme with ART, WAB and MP heralds on both sides rather quickly;
and most by 1959. The scheme with one railroad herald and the ART herald
was very short-lived. You mention that the Champ blue ribbon set had two of each
herald. Which heralds? If it was two WAB, two MP and two ART, that
is correct. What is the Champ set's number?
I missed the photo. Was it Ogden or Grand Junction? .
