Logo and insignia designs of European violent left-wing groups of the mid- to late-20th century. Five-pointed stars seem to have been mandatory.
Rote Armee Fraktion (aka the Baader-Meinhoff Gruppe, Germany, 1970-1998). Features a stylised Heckler & Koch MP5 machine gun.
Revolutionäre Zellen (Germany, 1973-1993). Curious typography.
Partido Revolucionário do Proletariado -Brigadas Revolucionárias (PRP-BR, Revolutionary Party of the Proletariat – Revolutionary Brigades, Portugal, 1970-2002). The only ones without a five-pointed star.
Grupos de Resistencia Antifascista Primero de Octubre (GRAPO, First of October Anti-Fascist Resistance Groups, Spain, 1975-2007). Nice colour scheme.
Devrimci Halk Kurtuluş Partisi-Cephesi (DHKP/C, Revolutionary People’s Liberation Party-Front, Turkey, 1978-present).
Cellules Communistes Combattantes (CCC, Communist Combatant Cells, Belgium, 1984-1986).
Brigate Rosse (Red Brigades, Italy, 1967-1988). This insignia appears to be a digitised version of the banner that was shown in the famous photograph of Aldo Moro taken during his kidnapping and murder in 1978.
Action directe (Direct Action, France, 1979-1987).
