Here we have an informational brochure entitled 'United States Customs Hints For Persons Entering the United States'. Written by the US Bureau of Customs and reprinted by the Cunard Line for their passengers. Undated but appears to be of late 1940's origin and obtained with other paper ephemera from a 1952 sailing. Measures 9 X 4 inches folded and 16 X 4 inches opened; printed on both sides. A charming relic of a bygone era of optimism and civility.
