Pierce Arrow Radio Grill

I have only seen that grill on 36-37 series cars. That said, a dealer could have installed it on an earlier car as part of a dealer supplied kit. It would not bother me to see it on any 1933-1938 series Pierce. 

Is it round?  The picture looks distorted.  34-35 coupes had a round grill and speaker above windshield.

Dave, yes it's round. It's also the only speaker grill I have ever seen that was factory installed.
