So my nephew is Swedish and lives in Gothenburg. He’s 5. Apart from small kids' stuff, my sister says she never saw comic books being sold in her town. My nephew’s favorite superhero is Spider-Man. On his last trip to Brazil, he loved my comic books. He cannot read yet, but my sister reads for him (she will skip anything inadequate for his age, of course. He can always reread later). She thinks he would prefer getting several small issues (48 pages usually I believe?) than a single book with the same page count (it's "more stuff" in his mind :P). The preferred languages are Swedish and Brazilian Portuguese (not European Portuguese). I would send him some in Portuguese but shipping would be slow and super expensive.

So, are Marvel’s monthly issues even published in Swedish? If so, how can she acquire those?
