Attilas äventyr #4

In "De hemliga uppfinningarna," Olle finds himself entangled in a new mystery when he stumbles upon a hidden laboratory at the castle, filled with strange inventions and a mysterious portal to another planet. With Attila and Z14 on his side, he must outwit a growing number of villains—all while the true mastermind remains at large. Written by Maurice Rosy, Maurice Kornblum, and Ingrid Emond, and illustrated by Derib, this 1983 adventure blends sci-fi intrigue with classic comic charm, all brought to life with Derib’s distinctive cover art.
