Emil Österman, one of the go-to society portraitists of the turn of the 20th century, has painted his friend Edvard Rosenberg in a monumentally conceived tribute, showing the artist concentrating for the next stage of his work on a large landscape painting. The portrait is dated 1901, the year of Rosenberg’s greatest triumph, when he was feted for the painting An Evening in March (Nationalmuseum) at a major international exhibition in Munich.
