Harkonmäki Collection
Matti Harkonmäki (b. 1935) sold his collection to the Helsinki City Art Museum in 1991. The collection was mainly assembled in the 1980s, comprising works mostly from that decade. Harkonmäki supplemented his collection especially with social realism from the 1970s, adding political and ideological features to the collection. The collection includes works by Marjatta Hanhijoki, Irina Krohn, Henry Wuorila-Stenberg, and Jarmo Mäkilä.
