The 1960s were marked by changes, conflicts and uprisings against the current systems. There were many worldwide protests against, among other things, the Vietnam War and the soviet brutal entry into Czechoslovakia at the same time as the race riots raged in the United States. 1968 was a year of many subversive events in the world and the exhibition The Nasty ones was a mirror of the contemporary political climate. In the foreword to the exhibition catalogue, Folke Edwards wrote about a new aggressive generation of artists who, with a social awareness, tried to protest against the evils of the world – against imperialism, racial oppression and biochemical poisoning. The exhibition was reported on several occasions when the works were not considered to be "art".
