Licensing

[edit]
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:
 This work is not covered by copyright.

This work was first published in Hungary in 1943 or before, and the identity of the author cannot be determined. According to the Hungarian copyright act of 1999 31. § (3): In the event the person of the author is unknown, the term of protection shall be seventy years and shall be counted from the first day of the year following the first disclosure of the work. For an explanation of the PD status in the US, see the template description page.

Important: "the author is unknown" is NOT the same as "I don't know who the author is". You have to provide a reason why you think no one else can know it; otherwise the image shall be deleted.

This work is in the public domain in the United States because it meets three requirements:

  1. it was first published outside the United States (and not published in the U.S. within 30 days),
  2. it was first published before 1 March 1989 without copyright notice or before 1964 without copyright renewal or before the source country established copyright relations with the United States,
  3. it was in the public domain in its home country (Hungary) on the URAA date (1 January 1996).
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.
