The above is the accepted symbol for the Deathly Hallows and is used by HP fans worldwide. However, while I was reading the books, the impression I got was of a slightly different symbol, namely:

This is because in the book, the symbol is most likely compared to being a 'triangular eye'

'The Cloak of Invisibility,' he finished, enclosing both line and circle in a triangle to make the symbol that so intrigued Hermione. 'Together,' he said,'the Deathly Hallows.' - *p332, Ch21: The Tale of the Three Brothers*

It struck me that the second symbol is much more likely to be mistaken for a triangular eye than the first. In addition, the way Xenophilius Lovegood drew the symbol also implies that the Wand's line was not meant to extend past the circle of the Stone. The circle was added **on top of the line**, not **on the bottom half of the line**. Admittedly, this is open to interpretation. 

As a follow-up question:
Has the symbol for the Hallows always been the first symbol, or was it changed when the movies came out?
