In 1931, Hergé’s second Tintin album was published. Even though Herge would later on continue to recognise ‘Tintin Au Congo‘ (and rework it for color print), this book suffered from the same ailment as ‘Tintin au pays Des Soviets‘, which Hergé would later denounce (and only allow to be reprinted in the 1980’s). Rather than the result of meticulous research, it was a roller coaster of an adventure set in a Central Africa that told the adventures of the young reporter in a Central Africa made up of caricatures and fragments of hearsay and missionaries’ memories.
In 2001 both the Belgian post office and the République of Congo issued stamps to commemorate this. Which was quite a unique event.
