Jouko Ruokosenmäki (b. 1968) is a comic professional from Tampere. He has drawn stories for the Finnish comics magazines Sarjari, Kannus, Tähtivaeltaja, Glömp, Myrkky and Korkeajännitys, with genres varying from adventure and horror to humor. Together with Janne Kaitala he created and self-published the Hipporox comic book in 1995, with the aim of combining all three genres. Was it a success? Who knows!
In addition to drawing, Jouko has translated comics such as Watchmen and Sandman, and back when comic books were still hand-lettered, he earned his living lettering Finnish Calvin and Hobbes albums. Since 1998 he has worked as a comic book editor and producer. Oh, and he also sat in the board of The Finnish Comics Professionals union for a few years.
