Nepraš’s sculptural and drawing oeuvre is one of the most prominent manifestations of the New Figuration movement of the 1960s, which he produced in a distinctive grotesque variant. The grotesque as a reaction to the absurdity and tragic-comic nature of human existence remained a characteristic feature throughout his oeuvre. Initially, he created monstrous-looking, expressively deformed figures, using the technique of assemblage. In 1969 he began working with iron which he had cast in modelled casting forms. The change of material brought simplification into Nepraš’s figural work; he also incorporated prefabricated industrial elements and simple movement mechanisms into his figures. However, during the period of political repression in the 1970s, he engaged in sculptural work only sporadically.
