Henrique Oswald Quartet: from left to right, you see Luiz Cosme (2nd violin); seated, Radamés (viola) and Sotero Cosme (1st violin); standing, on the right, Carlos Kromer (cello). In the center is D’Allor, a bassist who joined the quartet eventually. Curiosity: Sotero’s monocle and mustache were applied directly to the photo by Sotero himself, who, besides being a violinist, was also a designer and painter. Another cellist who was part of the quartet was the Italian Arduino Rogliano.
