People's Bicentennial Commission
The People's Bicentennial Commission (PBC) continued organizing after their appearance in Concord. They held a similar event to protest the US Bicentennial on the National Mall the following summer. The Vietnam War ended only days after the Concord Fight Bicentennial, but the PBC continued to advocate for nuclear disarmament, economic democracy, and an end to war and violence worldwide. The imagery of the American Revolution, such as the Gadsden flag ("Don't Tread on Me"), represented their belief that nuclear stockpiling and corporate greed were contrary to the values on which the country was founded.

The PBC marches over the North Bridge carrying a large American flag and a sign reading "Lay off profits not people," 1975.

A PBC sign placed in a tree which reads "Washington, wake up! Federal subsidies? STOP giving the rich our tax $! Jobs now!", 1975
The PBC and their leader, Jeremy Rifkin, were eventually investigated for claims of alleged communist affiliation. The Committee on the Judiciary, whose Subcommittee to Investigate the Administration of the Internal Security Act and Other Internal Security Laws carried out the investigation, published "The Attempt to Steal the Bicentennial: The People's Bicentennial Commission." The report contains exhibits of the PBC's publications, flyers, and more.
