Prototype: Swiss Phonograph by
»C. Sivan«, 1892
Sensational hand-signed and dated prototype
("No. 3" as marked) by the Swiss pioneer which announces the time.
Especially built for his "Talking Pocket Watch". The paper membrane of the
soundbox bears the
hand-written date 'Décembre 1892' and Sivan's signature. The original disc (2
1/6 in. / 55 mm) is signed too. A giant rarity in the history of
the phonograph and motion picture industries!
