English: As originally printed, the poster may or may not have carried a valid copyright notice. 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 1963 or 1964 (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 is a distinct work from the film it represents and had to be renewed separately.
Licensing
This is a faithful photographic reproduction of a two-dimensional, public domain work of art. The work of art itself is in the public domain for the following reason:
Note that it may still be copyrighted in jurisdictions that do not apply the rule of the shorter term for US works (depending on the date of the author's death), such as Canada (70 years p.m.a.), Mainland China (50 years p.m.a., not Hong Kong or Macao), Germany (70 years p.m.a.), Mexico (100 years p.m.a.), Switzerland (70 years p.m.a.), and other countries with individual treaties.
The official position taken by the Wikimedia Foundation is that "faithful reproductions of two-dimensional public domain works of art are public domain". This photographic reproduction is therefore also considered to be in the public domain in the United States. In other jurisdictions, re-use of this content may be restricted; see Reuse of PD-Art photographs for details.
