English: Poster shows no copyright markings; furthermore, a search with the Copyright Catalog (1978 to present) shows no copyright renewals for any poster artwork related to the 1930 film City Girl, therefore, even if the poster did bear a copyright, it is presumed expired. Copyright renewal was required by American copyright law to extend/maintain protection for works published in 1963 or earlier. In order to maintain copyright protection, the poster would have had to be renewed 28 years after publication. If not renewed, copyright lapsed at that time.
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 (50 p.m.a.), Mainland China (50 p.m.a., not Hong Kong or Macao), Germany (70 p.m.a.), Mexico (100 p.m.a.), Switzerland (70 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.
