Weihnachten im Liede is the title of a booklet with Christmas carols, produced as promotional gift by the German subsidiary of A.J. Polak, a manufacturer of custard powder, in Weener/Ems, East Frisia. There were at least four editions, each with a different cover typography.
Abraham Josef Polak founded the host company in Groningen, The Netherlands, in 1899. His uncle, Calmer Polak Gzn., had moved there in 1866 to trade in “colonial goods” and liquors, and became best known for his lemonade sirup brand “Ranja”. To distinguish the two entrepreneurs, uncle Calmer (1840–1922) was popularly called the “wet” Polak, while nephew Abraham (d.1924) was known as the “dry” one.

During the Second World War, the German occupiers introduced the “ordinance of expulsion of Jews from the business world” which meant the end for the Polak family, since they were of Jewish origin. While they were being deported to Auschwitz to be murdered, the factory kept running under a German manager. — Kantoor Groningen
In the course of this “Aryanization”, Wiard Popkes, former director of the factory in Weener, not only usurped the German subsidiary, he also became the new owner of the parent company in the occupied Netherlands—much to the chagrin of the managers of German industry giant Dr. Oetker, who had hoped to take over the Dutch competitor themselves.
