Known for his role in the prisoner's rights movement, Martin Sostre is often credited with having successfully implemented prison reforms from behind the bars of his own jail cell. As a revolutionary anarchist and anti-imperialist political prisoner, Sostre was a fierce advocate for the free speech, religious liberty, and due process rights of incarcerated people everywhere. As a bookstore owner and community organizer, Sostre brought his community together in Buffalo, New York, in solidarity against racism, classism, imperialism, and state oppression. Celebrate People's History with this poster, and celebrate Sostre's contributions to it. Put this poster up in your classroom, your office, your home, or wherever else Sostre's memory ought not to be forgotten.
