Working on the two original brass placards. They appear in previous posts but represent the 1) ownership by SO of NJ, and 2) the NC licensure plaque.

The placards are very thin, just between the thickness of foils and a tin can lid, and they are beat up and cracked. Help me out here. How would you preserve these with the intent of placing them back on the pump?

My thought was to use a slightly thicker sheet of brass and solder the placard to a suitable sized and shaped "backing" that would then support the rather fragile piece. Any suggestions?
