The art collection of Sigurd Frosterus (1876–1956) can be viewed as a declaration of love for the Colourism that emerged in Europe in the first half of the 20th century. Among wellknown names are artists like Magnus Enckell, Alfred Wilhelm Finch, Pierre Bonnard, Paul Signac, Thèo van Rysselberghe, Henri Edmond Cross, Maximilien Luce and Maurice Vlaminck.
