Josef Koudelka’s photos of the Soviets crushing the Prague Spring are everywhere here 
They were smuggled out of the country to the Magnum agency and not seen until 1969. Magnum did not initially credit Koudelka for fear the communists would target his family.
Rather fantastically there are huge blow ups of his shots on the streets where he took the pictures
As these are among the finest images of passive resistance, and the crushing of the Prague Spring convinced all except the most fanatical that communism was worthless, AND Josef Koudelka lived in exile in Britain, it would be great if a British gallery could show them
