"The 1980 Summer Olympics, officially known as the Games of the XXII Olympiad, was an international multi-sport event celebrated in Moscow in the Soviet Union. (...)
Led by the United States, 65 countries boycotted the games because of the Soviet war in Afghanistan, though some athletes from some of the boycotting countries participated in the games, under the Olympic Flag. This prompted the Soviet-led boycott of the 1984 Summer Olympics in Los Angeles. (...)"
This logo is not sth to desirable so much for my generation. I was a kid by that time, happy with big event, not understanding the cold-war-political background beneath.
One thing that definitely went down to the history from this Olimpic Games was a "Kozakiewicz gesture" - watch from 1:18 to 1:45:
The gesture itself (as described in a film) was a spontaneous and brave answer to the humming and whistling rUssian audience at the Olympic stadium - not being able to accept the clear skill superiority of Polish pole jumper over his rUssian competitor. You may not feel it - but for years on... even now we smile resembling this. And here again a salute to the Man - Władysław Kozakiewicz - for showing a "bent my d...k" to a hated ruler of our part of the world required steel balls.
