 While Kopecký was not the only Czech puppeteer, he became the most known one during the second half of the 19th century when his son Václav Kopecký published his plays in print, and due to a fictional picture of Kopecký by Mikoláš Aleš.In 1905, a small memorial to Kopecký was erected in Týn nad Vltavou and in 1947 another one in the castle park in Koloděje nad Lužnicí.The town museum in Týn nad Vltavou  hosts a permanent puppet exposition dedicated to Kopecký.
