This work is in the public domain in the United States because it meets three requirements:
it was first published outside the United States (and not published in the U.S. within 30 days),
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,
it was in the public domain in its home country (Austria) on the URAA date (1 January 1996).
For background information, see the explanations on Non-U.S. copyrights. Expired Copyright
For a simple photograph ("Lichtbild"), such as simple passport photos from Photo booths, photos from satellites, pictures from radiography, it was either published more than 50 years ago or it was taken more than 50 years ago and never published within 50 years of its creation.
Photographs that involve artistic interpretations, such as studio shots and those that involve lighting and poses, qualify as photographic works ("Lichtbildwerke") or "works of literature, music and art" (Eurobike: OGH, Beschluss vom 12.9.2001, 4 Ob 179/01d and Article 60). As such, a 70-year p.m.a. term of protection is applied (see this discussion).
In order to be acceptable on Commons, works must be in the public domain in the United States as well as in their source country. Austrian works are currently in the public domain in the United States if their copyright had expired in Austria on the U.S. date of restoration (January 1, 1996). However, some works might have a subsisting U.S. copyright resulting from the long-standing copyright relations between Austria and the United States.
