Hi Everyone!

I thought that when Harry checked the date on the HBP potions book 
that it was 50 years old... how can that be?  Snape could not have 
been around 50 years ago... is the book perhaps, secondhand?  Sorry if 
someone has already posted about this.  I just find it odd that the 
potions book is that old... and Snape wasn't around 50 years ago... I 
think there might be a clue there... any ideas... theories?
