Os Grandes Canhões Começaram a Troar [The Great Guns Have Begun to Thunder]

A colour photograph shows a US warship's gun firing over open sea, captioned as shells poured onto enemy defences ahead of a land invasion. The display of firepower and the verb 'vomit' aim to impress and intimidate rather than inform; the fear-appeal tag is weak, as the poster is mainly a show of strength.
