English: It is not possible to tell whether this poster, as originally printed, carried a valid copyright notice based on the scans available online, as these may have been cropped or otherwise modified. Regardless, 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 1961 or 1962 (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. Note that the ad art is a distinct work from the film it represents and had to be renewed separately.
