Is it a clue?

Perhaps everyone else has been seeing this for awhile, but I just 
noticed it.  At JKR's site, on the "Extra Stuff" page (coffee/tea 
cup), there is a scrap piece of paper hanging on the far right side 
of bulletin board with the words "Blood Prince" circled in red.  What 
caught my eye is what else is on that paper.  It looks to me like the 
side of a sketched lions mane, which of course leads me to the 
description of an unknown person she posted earlier.  So, do you 
think its a clue as to the identity of the Half-Blood Prince?
