The French glass factory d'Albret, started in 1918, by Roger Witking, began making sulfides in 1967 under the name "Cristalleries d'Albret", with Gilbert Poillerat, a noted French sculptor, producing the cameos.
Franklin Mint never produced any paperweights (as far as I know), but commissioned sulphides with Baccarat (and possibly d'Albret as well).
