The English editions of "Mosaik" have mostly appeared mostly under the name "Mosaic". Of Hannes Hegen's "Mosaik", issue 105, "Die Seeräuberburg", was issued in a limited run in 1965 in English as "The Pirates Castle". According to a former staff member at the publishing house, this was intended as a promotional issue for the United States market. An agreement had been reached to publish the comic books in the US; however, because of the US policy of economic embargo policy against Eastern European states in the Cold War, the contract could not be fulfilled.
