This recording shows Vladimír Boudník and his friends in an associative play on destroyed walls of Prague, completing stains in plaster with his drawings. The film was shown at a number of underground events even after Boudník’s death. The film was shot by Jaromír Pergler. The transfer to VHS was created in the 1990s. Since then, the film has been shown in the permanent exposition of Czech art in the National Gallery in Prague. The original reel is missing.
