As a potential example of the risks of drinking out of vintage ceramics, the old Jackson Ceramics site in Pennsylvania was declared a Superfund site because of excessive lead contaminaton.

I'm not sure if Jackson manufactured any mugs, but they did make plates, creamers, bowls, and other ceramics for Kon Tiki Ports, Ports O' Call, and other restaurants.
