Because I am not able to tell if this photo had a border which was cropped, a search for original copyright was done in artwork for the year
1942. There were no registrations for
Kriegsmann; there's no evidence of original copyright for the photo.
This work is in the public domain in the United States because it was
published in the United States between 1929 and 1977, inclusive, without a
copyright notice. For further explanation, see
Commons:Hirtle chart as well as a
detailed definition of "publication" for public art. 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.
