The custom official was desperate, he did not know whether they were pictures, wood ware or even arms [about his abstract collage art, Schwitters exported to France in 1939]. I got the impression he had an inner struggle with two options, either to have me arrested or to call the lunatic asylum. Finally he did not want to make a fool of himself, and accepted they were paintings, especially because another customs official knew me personally and confirmed that I was an artist.
