Le senhor Oliveira da Figueira et les aventures de Hergé et Tim-Tim au Portugal. By Albert Algoud and Philippe Dumas

In French, Editor Chandeigne, November 2021 , French language, Pages: 160 in colour, Softcover. 
In this book, we can discover the relationship between Tim-Tim and Portugal, starting with the fact that Portuguese was the first international language "spoken" by Tim-Tim. The good-natured character Oliveira da Figueira, who appears over the years in various adventures and in the most disparate places, is certainly the representation of Hergé's relationship with Portugal and his well-disposed biography is built here by Albert Algoud with illustrations by Philippe Dumas
