本作品在其來源國以及其他著作權期限是作者逝世後70年或以下的國家與地區屬於公有領域。

你必須增加美國公有領域標籤顯示為何這個作品在美國屬於公有領域。 請注意少數國家的著作權保護期為70年以上：墨西哥為100年，牙買加為95年，哥倫比亞為80年，瓜地馬拉與薩摩亞為75年，而這些國家不實施較短期限法則，因此該圖片可能在這些國家不被認為是公有領域。宏都拉斯的著作權期限一般為75年，但該國實施較短期限法則。對於在第二次世界大戰期間為法國利益戰死的法國人（更多資訊）、二戰期間參與過蘇德戰爭（俄羅斯稱之為偉大的衛國戰爭）的俄羅斯人，以及蘇聯時期遭到鎮壓，而死後獲得平反的犧牲者（更多資訊），這些人的作品著作權期限會有所延長。
