During the stunt, the 15-year-old Lucien Pepermans, a friend of Hergé's who had Tintin's features, arrived at Brussels' Gare du Nord railway station aboard the incoming Liège express from Moscow, dressed in Russian garb as Tintin and accompanied by a white dog; in later life Hergé erroneously claimed that he had accompanied Pepermans, whereas it had been Julien De Proft.
