His works are featured in many British history textbooks. On 1 September, the Germans invaded Poland from the west and, on 17 September, the Soviets invaded from the east. Low depicted these events in one of his most famous cartoons, "Rendezvous", first published in the "Evening Standard" on 20 September 1939. It satirises the cynicism which lay at the heart of the Molotov–Ribbentrop Pact, showing Hitler and Soviet dictator Joseph Stalin bowing politely across the dead body of Poland, but nevertheless greeting each other respectively as "the scum of the earth, I believe?" and "the bloody assassin of the workers, I presume?". The words are based on those supposedly used by Henry Morton Stanley at his meeting with David Livingstone in 1871, and the dictators are shown raising their hats to one another in greeting similarly to the two explorers in artistic reconstructions of that earlier meeting.
