Opak was a German quarterly cultural magazine which ran from April 2009 to February 2012. Founded by Oliver Koch, the former bassist of Tomte, each issue of the magazine was focusing on a specific theme, while also covering cultural news.
The magazine designers, Adeline Mollard and Floyd E. Schulze, used Simplon Norm and Simplon Mono, prior to their release, for its logotype and interior. Along the issues, some other fonts made appearance in the magazine, most notably SangBleu OG Serif (called Romain BP at the time) used for the review column spreads.
Some issues of the magazine can still be read online.
