The Scream of a Century - Apparently.
The 1913 Armory Show in New York City featured a painting by Edvard Munch, "The Scream", which caused a scandal due to its perceived obscenity and modernism. The painting was hung upside down to make it less visible, but it still sparked controversy and was eventually removed from the exhibition. This event marked a turning point in the art world, as it brought modern art to the attention of a wider American audience and paved the way for future avant-garde movements.
