This series consists of letters written from prisons. Most of the letters were sent to the New Panther Vanguard Movement headquarters in Los Angeles and included requests for literature and materials from the movement. Several prisoners also sent their own poems, drawings, essays, and other forms of self-expression. Some of them believe themselves to have been wrongly convicted and thus some have labeled themselves as political prisoners. For more “well-known” political prisoners see the series “Political Prisoners.” These letters provide a birds eye view into the prison experience and prison system.
