El Jueves: Suplemento Mensual

El Jueves: Suplemento Mensual was a short-lived Spanish comic series published by Formentera from 1979 to 1982, running for 16 issues. As a monthly supplement to the long-running humor magazine El Jueves, it offered a platform for edgier, more experimental satire and cartooning during Spain's post-Franco transition.
