On this book jacket from 2019, Marvin Visions (2017), a revival and expansion of Marvin (1969), is used to epitomize the 1970s, alongside the psychedelic background of rainbow-colored swirls complete with florettes, stars, and peace symbols.
From the publisher (translated):
Jens Balzer, one of Germany's most distinguished cultural journalists, paints a colorful panorama of the seventies, from the moon landing and Woodstock to the oil crisis, the German Autumn and the nihilism of punk. A decade in which pretty much everything changed: The hippies try out unheard-of lifestyles, anti-authoritarian education and the emancipation movement reorganize family and gender relations, global idealism meets apocalyptic fears of the end of the world, and when hackers build the first “personal computer” at the latest, it becomes clear: this is exactly where our present begins.
