Fair use rationale: picture is from period 1919-1928 (when aircraft was in use by Argentine Naval Aviation), hence copyright expired (see rationale used in "ARA Garibaldi" image, similar case to this pic).

"...This image is in the public domain because the copyright of this photograph, registered in Argentina, has expired. (Both at least 25 years have passed after the photograph was created, and it was first published at least 20 years ago, Law 11.723, Article 34 as amended, and Berne Convention Article 7 (4))."
