After Berlin came Prague and the Velvet Revolution. Every evening for nearly a week, up to 500,000 people protested peacefully in Prague's Wenceslas Square. In 1968, the great Czech photographer, Joseph Kouldelka, made an image from the same spot of an empty square as the population defied a decree to appear, en masse, in support of the then-Soviet-backed regime. This image was made in honor of Kouldelka and all of his fellow compatriots. 1989.
