Abijah,
Not so much as a stamp, as a printing plate. Before ink jet printers, they would ink these up, and press paper against them.

Abijah,
The dial on the right sets the resistance in Megaohm as far as I can read. If I see that correctly its the printing plate for manual for an old X-Ray machine. Only those kathode tubes (at the bottom) would akquire such high voltage (200V)
