Frank,
Basically I asked a friend of mine that works with photo shop ago create a digital file of the plaque..(attached on this email) I took as much all dimensions as possible and also scanned in real size to help him.
Than I went to a arts store and bought a paper which is double sided and with glue on it. You print, peel and apply to the metal plaque. It needs to be absolutely clean to add the film on it. I'll check and see if there is any name on the paper to help.
Regards,
Caio
