Hard to believe, but it's true. Harry Potter turns 20 this week.
It was 20 years ago when Harry Potter and the Philosopher's Stone was published.
Joanne (aka JK) Rowling finished the manuscript in 1995, and the first hard copy came out on June 26th 1997, and only 500 copies were printed.
Then something magic happened. That first book - and the six that followed - went on to sell more than 450 million copies around the world.
