This image (or other media file) is in the public domain because its copyright has expired.
This applies to the United States, Canada, the European Union and those countries with a copyright term of life of the author plus 70 years.
Note that a few countries have copyright terms longer than 70 years: Mexico has 100 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.

This image shows a flag, a coat of arms, a seal or some other official insignia. The use of such symbols is restricted in many countries. These restrictions are independent of the copyright status.
