This year, on the 26th of June, Harry Potter turns 19.
The first Harry Potter book came out an entire late-stage teenager's lifetime ago... You could be taking your A Levels right now, having never lived in a world before Harry Potter. Let that sink in for a second. An entire human adult lifetime since we were first introduced to the boy who lived (in a cupboard under the stairs). In fact, most people born after it came out might well be living in a cupboard soon!
But, look on the bright side. If Harry Potter and the Philosopher's Stone were a person, it'd be old enough to get some pretty sick tattoos... just like its fans! Take a look at a few of our favourites below.
