English: Scan via Heritage Auctions.

English: Illustrator unknown, likely a work-for-hire on behalf of the film's American distributor United Artists. Printed by M. R. Litho Co. in New York, per the credit seen on the bottom-left corner.

English: The poster did not include any copyright notice under the formalities of American copyright law for the time. Even supposing that other copies did, the copyright for the artwork was not renewed, as was required by American copyright law to extend/maintain protection for works published 1963 or earlier. In order to maintain copyright protection, the poster would have had to be renewed 28 years after publication, in either 1959 or 1960 (see the sections for "Artwork: Original registrations and renewals" and refer to the links to search the copyright catalogs for those years). Because it was not renewed, copyright lapsed at that time at the latest. Note that the poster art is a distinct work from the film it represents and had to be renewed separately.
