STOLZER (E.) ? The Matterhorn and the Black Lake. About 1920. Oil on canvas, signed lower left, 73.5 x 62.5 cm, framed. A large and beautiful view of the Matterhorn reflected in the Black Lake in Zermatt. A classic composition by an unknown but clearly inspired painter, giving us a Matterhorn that Charles-Henri Contencin or Edward Theodore Compton would not have disowned.
