Denne skabelon skal kombineres med en licensskabelon for USA, der angiver hvorfor dette værk er offentlig ejendom i USA. Bemærk at i et mindre antal lande varer ophavsretten længere end 70 år: Mexiko har 100 år, Jamaica har 95 år, Colombia har 80 år og Guatemala og Samoa har 75 år. Dette værk er måske ikke offentlig ejendom i disse lande, som ydermere ikke afkorter beskyttelstiden til maksimalt den i hjemlandet. Honduras har en generel varighed på 75 år men der afkortes beskyttelsestiden til den i hjemlandet.
