Peter Sis on the Prague Spring, here.
Here is an excerpt:
I drew and drew. The more repressive the outside world became, the more freedom I found in drawing, in creating a world for myself. I decorated the whole house we were living in from top to bottom, the light switches, the door of the fridge, the chairs. I drew at school, through all my classes, even math and physics (so don’t ask me about electricity, or how to count). My art highschool was a wonderful time of my life. Life was relatively freer than it had been, with the advent of the Beatles, the summer of love, and The Prague Spring. What wonderful synergy. Then the soviet tanks rolled in to Prague, and everything crashed down. It is hard to see what is happening as it happens in history. You go with the flow, and only see things clearly many years later.
