 The last exhibition organized by Chalupecký consisted of paintings by Vladimír Kopecký in May 1970.In the 1970s and 1980s, after the defeat of the ‘Prague Spring’ reform movement, Chalupecký was under a State ban and could not publish or be employed in his field.The gallery programme at this time was determined by the Association of Czechoslovak Fine Artists (Svaz československých výtvarných umělců), which was subservient to the régime, and the importance of the gallery declined.
