Robert Stolz, his signature on the 1970 Austrian Pamphlet. This pamphlet holds a special postage stamp from the series "FAMOUS OPERETTAS," issued by the Austrian Postal Administration in 1970 to commemorate Prof. Robert Stolz's 90th birthday. Featuring the motif of the operetta "TWO HEARTS IN THREE-QUARTER TIME," this stamp is the only one ever issued by the Austrian Postal Administration to honor a living personality, excluding the  Federal President.While Robert Stolz's rare signature, appearing twice on the pamphlet, is the main feature of this lot, the pamphlet itself commemorates his remarkable career and legacy in music. Dedicated with best wishes to all philatelists worldwide.
