Strict government censorship prevented "La Silhouette" from publishing caricatures aimed directly at politicians – except for a small woodcut of the king (Charles X of France) by Philipon that was surreptitiously inserted within the text of 1 April 1830 issue. The newspaper had never included engravings in this way it was overlooked by the censors who were concentrating on the issues' lithographs. The publication caused a scandal – with an intensity that reflected the rarity of political caricature before the Revolution – and the editor was eventually sentenced to six months in prison and fined 1,000 francs. Philipon, who had carefully left the caricature unsigned, escaped the scandal's repercussions.
