Cid tried several jobs but his career as a
caricaturist and a cartoonist only took off after the
Carnation Revolution of 25 April 1974 when the censorship imposed by the
Estado Novo dictatorship was lifted. His first published cartoons were with
Povo Livre, the official organ of the then
Democratic People's Party (PPD), a right-of-centre party. He also designed the PPD's logo. Later he published in newspapers such as
O Diabo,
O Independente,
Grande Reportagem and
Semanário, a weekly journal founded by, among others, the present president of Portugal,
Marcelo Rebelo de Sousa. His controversial cartoons often attacked extreme left politicians such as the
Communist Party leader
Álvaro Cunhal. Despite the lifting of censorship, two of his books,
O Superman and
Eanito, el Estático, both poking fun at
António Ramalho Eanes who was the president between 1976 and 1986, were seized as a result of court orders. In addition to his artistic work, he was noted for his commitment to identifying the causes of the
1980 Camarate plane crash in which the president,
Francisco de Sá Carneiro and
Adelino Amaro da Costa, the first civilian defence minister after the revolution, were killed. Cid was convinced that the plane had crashed as a result of a bomb and it was largely due to him that the idea that it was not an accident emerged. The actual cause has never been satisfactorily resolved. ==Sculpture==
