From this base post-war, Rosenberg managed to reclaim and re-purchase a number of pieces from his pre-war collection, but these represented less than half of the works he had lost. After the end of hostilities, he personally travelled to Paris to hear the tales of the family chauffeur Louis, who told of the coming of ERR trucks not long after the family had departed. On this first trip, Rosenberg managed to regain the 1918 Picasso portrait of his wife and daughter—one of three—renamed by Göring "Mother and Child"—from a small museum in Paris.
