Archaeo-bloggers Gill and Barford now have Smithsonian Magazine in their sights for publishing pictures of undocumented Mayan artifacts. See

and http://paul-barford.blogspot.com/2011/06/looted-pots-in-smithsonian-magazine.html
This is yet more overkill. The AIA's policy against publication of undocumented artifacts was originally meant to ensure that papers were properly documented from a scientific perspective. But Smithsonian Magazine is meant for a general audience. And, as a subscriber, I'm happy Smithsonian does not limit its illustrations only to artifacts from documented archaeological excavations.
