From what I hear (I'm here at the Europeana
conference now where they are
officially launching the PDM tomorrow - as per the press release
http://creativecommons.org/press-releases/entry/23755 ) CC were debating
whether to use a logo that was "C-with-a-line-through-it" or the letters

an "anti-copyright" logo which is not the message that CC wants to send out.
But, they ended up choosing it largely because Wikimedia has already made
the image recognisable through templates like "PD-old"

the creation of this Mark even though we didn't know it :-)
