            The official  position taken by the Wikimedia Foundation is that "faithful reproductions of two-dimensional public domain works of art are public domain, and that claims to the contrary represent an assault on the very concept of a public domain". For details, see  Commons:When to use the PD-Art tag. This photographic reproduction is therefore also considered to be in the public domain.  Please be aware that depending on local laws, re-use of this content may be prohibited or restricted in your jurisdiction. See  Commons:Reuse of PD-Art photographs.
