On May the 14th there is Free-Comic-Day in Germany, Austria and Switzerland! Everyone who visits one of contributing shops, gets one comic for free. There are thirty comics to choose from: Manga, superheroes, Disney and also independent ones. The works are (translated) in(to) German language.
And yes, there are also some science-fiction themed, like “Die Überlebende” (original title: “La survivante” – that means “The Survivor”) by the French artist Paul Gillon where a woman finds herself as the only human survivor in a post-apocalyptic word. It is a classical work from the 80ies. (Please note that the story is not recommended for children, but for adults and teenager who are at least 16 years of age!)
Furthermore, some of the shops celebrate this special day with further exhibitions, competitions or artist´s signings.
