Tintin au Congo - red spine - B2 back without title
A copy called ''universel'' or ''avant la lettre'', without texts in the speech bubbles and without title on the front cover,
The comic book is a prototype that was used at the end of the forties by a representative of Casterman for presales abroad. That's why the album has no title on the front cover and no text in the speech bubbles.
In perfect condition, only opened a few times. One of the rarest Tintin albums.
