Otniel Sobek, autographed picture
On that cold morning of February 23, Otniel Sobek woke with a strong idea in his mind. He had collected autographed photos of the main singers who appeared in the Vienna State Opera, but lacked the one of that young Swedish tenor that had already been presented there the year before singing Il trovatore, Aida and La bohème. Such was his success (despite he sang his roles in Swedish while the rest of the cast did it in German), that in 1937 he was again hired to sing nothing less than eight operas: La bohème, Il trovatore, Madama Butterfl y, I pagliacci, La fanciulla del West, Faust, Un ballo in maschera and Rigoletto.
