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.
