Did all 70 Buicks have the Buick name on the Radio?

Just wondering if the Buick name on the radio buttons was standard back then or was it an option? More specifically the GS of 1970.
Anybody know for sure?

 

I believe only pre 70 model Buick radios had the word Buick on the radio buttons.

 

thanks Jim
So then the factory did not put any radios like that in ANY 70 stuff?

I could swear my 71 skylark had that kind of radio in it.
But then again I forget things way to easy now days.

 

Some of the early cars had "Sonomatic" on the face, AL.
