QRN sur Bretzelburg.

QRN sur Bretzelburg (Eng. Lit., QRN over Bretzelburg), written by Franquin and Greg, drawn by Franquin with assistance by Jidéhem, is the eighteenth album of the Spirou et Fantasio series. The story was initially serialised in Spirou magazine under the name QRM sur Bretzelburg over an unusually long period (including a break in 1962), before a delayed hardcover album release in 1966.
