Here's a very rare Rosenthal advertisement ashtray made for the Spanish export market that is marked in beautiful gold leaf: "Rosenthal, Productos Para Laboratorios." (Rosenthal Laboratory Products). On the base it is also marked: Rosenthal Marktredwitz Germania, (Aust Crt?) Technische Porzellane. This item is highly sought after by pharmacists and Rosenthal specialists. Mint condition. First email gets this for only $55 plus shipping. Thanks
