I think the mask was old enough, but I'm not sure. The technology has changed for the better apparently.
I just learned of a different way of describing dates. BP, which is "before present" referring to dates before January 1, 1950. Somewhat randomly chosen, but tied to both the beginning of carbon dating, and the proliferation of nuclear testing which altered the radioactive carbon available enough that it has to be accounted for.
