First published in December 1955, it is the longest-running German (and European) monthly comic book and the only one originating in East Germany that still exists.
[citation needed] At the height of its popularity, prior to German reunification, Mosaik had a print run of almost a million copies per month.
Reaching an agreement with Neues Leben, Hegen created the first issue of Mosaik for publishing in December 1955.
Mosaik was published quarterly until July 1957, when it switched to a monthly schedule that has continued uninterrupted to this day.
There is also a promotional flyer for these issues, which states that the Mosaic with the Abrafaxe is published in English and Arabic in addition to German, advertises for subscriptions, and includes an order form.
