Grzegorz Janusz and Krystof Gawronkiewicz are the writer and artist of the multivolume Adventures of Otto and Watson. The draft version of the first volume, Essence, won the first European Comic Book Competition, hosted by the television company Arte and the publisher Glénat, beating six hundred other drafts from all over Europe. As a result, it was published in French (Glénat, 2005) before it was published in the original Polish (Mandragora, 2006). The second volume, Romantisme, was published by Glénat in 2007.
