Aquest material està en domini públic als Estats Units i als altres països on el dret d'autor s'estén per 70 anys (o menys) després de la mort de l'autor. Cal incloure una etiqueta de domini públic als Estats Units per indicar perquè aquesta obra és en domini públic als Estats Units.  Note that a few countries have copyright terms longer than 70 years: Mexico has 100 years, Jamaica has 95 years, Colombia has 80 years, and Guatemala and Samoa have 75 years. This image may not be in the public domain in these countries, which moreover do not implement the rule of the shorter term.
