Ruukki is sponsoring an exhibition that will feature Finnish sculpting artist Kari Huhtamo works and graphic prints over a period of nearly 30 years. The sculptor, Kari Huhtamo, is known for his distinctive, freely expressive style. The motifs in his works often refer to nature. The principal material in his sculptures is steel. Steel is a versatile material with a homogeneous surface which can be moulded to suit designs of different sizes. The majority of the pieces to be displayed in the exhibition are made of steel. The exhibition, which is called Variatio arctica sculptura, will be open in the Tretyakov Gallery in Moscow from 3 September to 4 October 2009. The patron of the exhibition is the President of Finland, Tarja Halonen. Ruukki is the main sponsor. Other supporters are the Finnish Cultural Foundation, the Alfred Kordelin Foundation, the National Council for Visual Arts, the Ministry of Education, the Ministry for Foreign Affairs in Finland, the companies Sanoma Magazines B.V. and Finntemet Oy and Frame.
