Gallery "Meno parkas" and West German Artists' Association has been successfully collaborating for 20 years. Numerous joint exhibitions and projects were implemented during this period of time. Artists from both countries took part in organized international symposiums, reciprocal visits, artist meetings and discussions allowed to create close relation between the two associations. The project "10 + 10 = 20" outlines the period of collaboration and presents three exhibitions, two of them will take place in Germany (Münster and Enniger), and one will be held in October at gallery "Meno parkas" in Kaunas. Ten artists from both countries take part in each exhibition and presenting paintings, sculptures, installations and video works.
