It is, however, not the same license as specified on upload, which was the cc-by-sa-2.0, and it is unknown whether that license ever was valid.
This image was taken from Flickr's
The Commons. The uploading organization may have various reasons for determining that no known copyright restrictions exist, such as:
The copyright is in the public domain because it has expired;
The copyright was injected into the public domain for other reasons, such as failure to adhere to required formalities or conditions;
The institution owns the copyright but is not interested in exercising control; or
The institution has legal rights sufficient to authorize others to use the work without restrictions.
