Jaan Grünberg is a rare example of an artist, the best examples of whose creation originate from a rarely used technique: the monotype. It is a technique, which presupposes the artist’s exceptionally good sense of colours, as it is impossible to preserve exact brushwork from the proof, being taken from the glass. Grünberg, who repeatedly studied and worked in Paris, is undoubtedly one of the brightest colour masters of the local art history. Still, the creative period, which is unanimously called his most important one, arrived only by the time Grünberg was 50 years of age. He was again staying in Paris, where he initially arrived in 1926 after graduating from “Pallas” thanks to a scholarship. Hilja Läti’s evaluation to Grünberg as “the most remarkable follower of the late French impressionism” and “an outstanding colourist” received its proof only then. The artist worked actively and mainly with monotype, which his good acquaintance Marc Chagall recommended to galleries (!). In the first range he took interest in cityscapes and landscapes, which he usually depicted without people. This confirms us of which Grünberg was the most inspired by: colours offered by nature.
