This signature is believed to be ineligible for copyright and therefore in the public domain because it falls below the required level of originality for copyright protection both in the United States and in the source country (if different). In this case, the source country (e.g. the country of nationality of the signatory) is believed to be Бразилия.
Note that this tag cannot be used on all signatures, as not all signatures are copyright-free.
There are some court cases related to threshold of originality in Brazil. According to one study, and the court decisions contained in it, the concept of creativity in Brazil is way more strict and exigent than in the United States, and consequently the threshold of originality is considerably higher than the United States, which is the general reference in Commons. See COM:CRT/Brazil#Threshold of originality for more information.
