DAM SQUARE, AMSTERDAM, NORTH HOLLAND, NETHERLANDS - 2019/05/11: Vegan activists seen wearing Guy Fawkes masks while holding placards during the demonstration. Hundreds of activists gathered at the Dam square in the center of Amsterdam to participate in The Cube of Truth. Anonymous for the Voiceless hosted a 24-hour Cube of Truth in Dam Square, Amsterdam. The Cube of Truth is a peaceful static demonstration similar to an art performance. This demonstration operates in a structured manner that triggers curiosity and interest from the public; the activists attempt to lead bystanders to a vegan conclusion through a combination of local standard-practice animal exploitation footage and conversations with a value-based sales approach. They protected their identities by wearing Guy Fawkes masks and black clothes. (Photo by Ana Fernandez/SOPA Images/LightRocket via Getty Images)
