Brought the family to Williams, AZ to ride vintage train 63 miles to south rim of Grand Canyon. Spent today looking in all of the Route 66 shops in Williams. After three hours looking at all the signage for sale, I can assure you that not one store has any KF OR Henry J signage. However, a vintage gas station museum in town has a photo on wall of a 48 Kaiser getting gas at that very station in 1949. I took picture but too much flash glare in photo.
