There was one image in particular I wanted to use and after much debate and
searching I decided there was sufficient evidence to suggest it was under a
free software license. The image I wanted to use was on the t-shirt of the
LibrePlanet 2010 conference. It said LibrePlanet and "Working Together for
Free Software" with all the free software project characters on it.
The image was posted to the LibrePlanet wiki by Matt Lee who works at the FSF
and then that page was updated by Peter Brown (executive director of the Free
Software Foundation at the time of posting).
The content on that page was suppose to be under a free software license and
given the poster and whom updated the page it is fair to say it was:
