A beautiful set of 5 'Tulipa' graduated clear and smokey glass candle holders designed by Bjørn Wiinblad for Rosenthal Studio Line, and produced for only a short time in the early 1960s. Each candlestick is mouth blown to form a smoke gray tulip-form top on a clear crystal stem and base. Each is etched with the Rosenthal crown and 'R', and one retains its gold foil label. The entire set is in excellent undamaged condition, and measures between 22cm up to 55cm. There is some light wax residue inside the holders, which we have left untouched. Soaking in hot water will remove it if desired.
