Did you know that Luxembourg has its own superhero? If you have never heard of De Superjhemp (sometimes written Superchamp in English), you’re in for a treat. Superjhemp was first launched in 1988 as a superhero in a comic strip. The character was first created by illustrator Roger Leiner and writer Lucien Czuga. Since then, he has appeared in over 29 graphic novels which have the highest sales rate for Luxembourgish publications.
