In this fascinating collection of photographs from the 1970s, the hippy movement of Soviet Estonia is captured. Behind the iron curtain, western freedoms were coveted and a peace-and-love counterculture emerged that was detached from the official Soviet ideology.

The fabulously out-there fashions and long hair are all on show here, and you get the sense that in Soviet-era Estonia this was a truly radical movement, viewed by the authorities as a real political threat that had potential to subvert the ruling regime. Soviet flower power became ever more absurd in its aesthetic, but also curiously brave, creating its own haven of optimistic hippiedom.
