Adhesive Metal Decals for boards.

Remembering old makers who used to put adhesive metal foil name plates on the surface of their boards… Might have been Aluminium ? 

 Not sure if they resined them on or what glue they might have used but they were a metal foil, many were embossed, some flat and had coloured writing or images.  

They lasted well for decades so I’m thinking about reviving them for my own boards. Anyone else using them or know any more about them ?

 I’ve contacted some industrial label makers to see what they can come up with for me.
