Tenga en cuenta que algunos países tienen términos de derechos de autor más de 70 años: México tiene 100 años, Jamaica tiene 95 años, Colombia tiene 80 años, y Guatemala y Samoa tienen 75 años. Esta imagen puede no estar en el dominio público en estos países, que además no aplican la regla de corto plazo. Honduras tiene un derecho de autor general de 75, pero aplica la regla de corto plazo. Esto está sujeto a la leyes respectivas sobre los derechos intelectuales.
