It seems almost crazy to take t-spoons of Beedle the Bard from Amazon, and fitting them into canon! (If Amazon.com transmission of information can be considered canon - which I don't think it can).
Yet the Bookstore confirms that the (Hallows) symbol in the book (BtB), on page 141, first page of the story called "The Tale of the Three Brothers" appears on the forehead of one of three skulls. They say that it is a triangle with a circle inside it and (a) line through the center.
I could really see this thing boosting LL posts. I think it's safer than posting on Amazon.com, to be honest. Particularly if your personal AMAZON information can be viewed by anyone browsing the "Beedle" site. ELC suggests CAUTION!!
