Restoring Jaguar name plate on boot/trunk plinth

Has anyone restored the Jaguar name plate on the boot/trunk plinth, or can advise if the Jaguar name plate is painted on reverse of the clear plastic name plate, or is a printed name plate glued to back of the plastic?

The name plate on my 1978 pre he is starting to delaminate or peel off in parts due to 42 years exposure.

Thanks Al
