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 (Switzerland) on the URAA date (1 January 1996).
For background information, see the explanations on Non-U.S. copyrights. The Swiss copyright on Mittelholzer's work's expired at the end of 1987, since Switzerland had a copyright term of 50 years p.m.a. until 1993, and the extension to 70 years p.m.a. made in 1993 did not restore already expired copyrights.
