Kozłowski arranged a “reception” of the materials that the recipients of NET had sent him in response to the proposal in his apartment in Poznań on the evening of May 22, 1972. Though the reception was a way of sharing the materials that had arrived in the post (“after a month or two all sorts of mail arrived”) from twenty-four of those to whom they had sent the proposal, it was more informal than an exhibition, with materials hung all over the place, piled up on tables, and arranged on the floor for lack of space. Among them was Perneczky’s series on the theme of identification, suspended above a desk. Kozłowski had written to Perneczky (in German) in March 1972 after receiving a card from him, promising to put him on the NET appendix and send him a copy soon. He explained that he was planning to present the NET materials received to date in May and asked to include “Deine Concept Art.” The artist had invited just ten close acquaintances to the reception, making the raid that occurred forty-five minutes after the invitees arrived all the more shocking, since it was clear that one of his friends had informed on him. The materials were duly confiscated, including the film from the camera used to document the meeting itself: “They took it all down and took it away.”
