The Youth Revolt Across most of the Western world, a movement made up mainly of young students started in the late 1960s and early 1970s. It has later been dubbed "The Youth Revolt" or "the 68 Revolt".

The young students who participated in the revolt were protesting against the lack of democracy in the way their educational institutions were run, bad housing conditions, especially for young people, the nuclear arms race, the USA's war in Vietnam and western imperialism in the Third World in general.

Their criticism developed until it encompassed the whole capitalist social system, which the young activists thought was based only on consumerism and the individualist rat race. They turned against the authorities in general and on the education system in particular. Some youngsters set up collectives, lived as socialist communities, let their hair grow and wore psychedelic clothes. The hippies, as they were called, experimented with hash and LSD and tried to live according to the socialist ideals inspired by communism in China, Cuba and Vietnam.

The stamp motif was drawn by Bo Bojesen for the satirical magazine Blæksprutten (the Octopus) in 1969.

It shows how Bo Bojesen imagined the Rector of the University of Copenhagen, Mogens Fog, welcoming new students in the future.

In 1969, several hundred new students decided not to participate in the official and very stylish welcoming ceremony. They attended a very informal get together in the University Senate Yard instead, drinking bottled beer and playing bongo drums.

Mogens Fog understood and respected the revolt. He was even seen wearing a badge on the inside of his jacket lapel bearing the words "Participatory democracy now!".

The students also knew how to show their respect in return. Several of the banners that students carried on demonstrations bore the legend "We love Fog".

Bo Bojesen (born 1923) originally studied at the Danish School of Art and Design. He began to draw for magazines and satirical periodicals in 1943. His almost daily drawings in Politiken from 1947-92 included a whole series of archetypal and immortal Danish political caricatures.

One of the most famous pictures of the time featuring the author Klaus Rifbjerg and the historical consultant for the 20th-Century stamp series, Ebbe Kløvedal Reich, smoking hash on the stairway of the Ministry of Culture.

They were not demonstrating for the legalisation of cannabis. It was a protest against the Ministry of Culture's criteria for cultural grants. Inge Krogh of the Christian People's Party had spotted people smoking hash at a performance by the theatre group Secret Service in the cellar theatre in Farvergade, Copenhagen. The premises had been put at their disposal by the Ministry of Culture but were closed as a result of the complaint and the group lost its subsidy.
