1970 poster for the Black Panther Party calling for a "Revolutionary People's Constitutional Convention." The backdrop to the poster includes an image of Bobby Seal tied to a chair, which was during a trial. The bottom of the poster says "The Shackling like a Slave of Black Panther Party Chairman Bobby Seal is like the Reincarnation of Dred Scott 1857. This Brazen Violation of Bobby Seale's Constitutional Rights Exposes Without a Doubt that Black People have No Rights That Racist Oppressor Is Bound to Respect."
