Is this Photographic proof that some of the Dealership's that were expecting to handle and prep the true Pace Cars replicas took Jack Bell's advice to " Get The Word Out as early " as possible?? I believe it is!
This image is from an Indianapolis area yearbook Ad. The Photo was probably taken as early as late January and as late as early March based on most yearbooks would come out in June.
The graphics on the Door Decal may look oddly familiar since they appear to be a mix of the typical period graphics ( Font and such ) used by the Speedway and Chevrolet.

Looks like that car may have headrest, too.
