If you were to scan this black and white footage very briefly, it would simply look like a traditional Christmas celebration in the 1940s.
But the happy children singing carols are actually doing so under a Christmas tree topped with the Nazi symbol, the Swastika.
They're also receiving presents from high-ranking Nazi officials.
The chilling footage was filmed in December 1940, during the Second World War, and it shows how Adolf Hitler and the Nazi Party celebrated Christmas.
All this was taking place as millions of Jews were being sent to concentration camps.
The re-surfaced footage really reveals the festive vision that the Nazi propagandists marketed to the German public.
