S.O.S. na Idade da Pedra (Suplemento do Jornal do Cuto)

Roussado Pinto, writing under the pseudonym Edgar Caygill, and artist Vítor Péon launched this single-issue Portuguese comic as a supplement to the newspaper Jornal do Cuto in 1977. A prehistoric adventure strip, S.O.S. na Idade da Pedra represents a distinctive piece of Portugal Press's publishing history, showcasing Péon’s signed artwork and Caygill’s storytelling in a compact, one-shot format that has never been continued.
