Edward Krasiński created his 1975 work Interwencja (Intervention) in his own technique on fibreboard, using the artist's characteristic blue scotch. One of the main protagonists of the Polish avant-garde of the 1960s and 1970s, co-founder of the 'Foksal Gallery' in Warsaw,
he was a painter, author of sculptures, installations and spatial forms, and initiator of artistic events. However, the most important aspect of his activity was his life and creative attitude, which expressed itself as 'life in art'. From 1968, Krasiński began to identify the space of his art with a blue strip of adhesive tape, placed at a height of 130 cm. It soon became the artist's trademark, sometimes interpreted as a visualization of linear time. Krasiński combined the Constructivist tradition with Dadaist humor in his works. However, he disagreed with those critics who attributed conceptualism to his art: 'What I do is as real as possible, to the point of disgust!'
