 : I think I've got an answer - http://www.dead.net/sites/default/files/images/19680718_0286.original.jpg ... if my understanding of our file copyrights is correct, that is a trade advertisement published by Warner Bros Records c. 1969 with no copyright notice on it, and therefore is PD in the US. Does that sound about right? In which case, we have a free infobox image of Pig, not a great one and not as good as the one that was there, but if it's PD and good enough it has to trump any non-free image.    "
