Each generation is defined by an image. Perhaps for the 90s it was the grunge movement. For the 80s, the iconic figure of Madonna. For the 70s, a techno and disco print. For the 60s, a snapshot of Woodstock and on and on. You get the idea. For every 100 years, there is an event that defines a generation and for every event, there is an image that captures that moment. While you may not agree with the imagery listed here, you cannot deny amazing the endurance of their existence in pop culture.
