Guastavino Company tiles. These from New York State but the fireproof vaults and domes they were made into live in other places too. Started by Spanish immigrant Rafael Guastavino, the firm went on to greatness under his son of the same name. Much work in the subways but also at Ellis Island and the Cathedral church of Saint John the Divine.
