English: The poster does not appear to have included a copyright notice. However, even if there had been a notice—if, e.g., this is a cropped version of the full poster paper—the poster is still in the public domain due to a lack of renewal. 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 1960 or 1961 (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 poster art is a distinct work from the film it represents and had to be renewed separately.
