This cartoon was drawn at a time when political and social causes were in decline and individualism and consumerism were on the ascendant. It shows a teenage girl (who is very concerned about fashion and branding) asking her mother (who in her youth was a social activist) which brand the CND logo represents, as the girl doesn’t recognise it as the symbol of a campaign group.
Now (2021) there is a resurgence in social and political activism, however some of the campaigns are deliberately adopted by commercial organisations to boost their profile in the social concern stakes. A typical example is the commercialisation of Gay Pride.
