In the 1970s-1980s, Marian Kropyvnytskyi had meetings with prominent Malevich experts, Dmytro Gorbachev and Oleksandr Parnis. He gave the latter a copy (one sheet) of the meeting minutes of the color section of the faculty of formal-technical disciplines. Then, Kropyvnytskyi made no mention of his private archive. It is possible that he did not know of their inclusion in his papers, or could not find the relevant documents, or forgot about them, or did not wish to talk about the collection.
