Old California Shield in Commercial

As I was walking back to my office with my lunch, the TV in the cafeteria (which normally plays either CNN or Fox News) had on a commercial for Super 8 Motels. What caught my eye in this commercial was an Ohio road sign, followed by a current California road sign, followed by various license plates. Then, near the end, they showed a pre-1964 Calfornia white bear shield sign for Route 11. None of those are up anymore, so I’m wondering what prompted them to use this sign, and where they found it.

Has anyone else seen this commercial?
