Fans of the Harry Potter book series — and now, franchise — are a devoted bunch who have helped the success of the seven-volume series. Since the first book, "The Philosopher's Stone," was published in 1997, over 450 million copies of British author J.K. Rowling's young-adult fantasy series have been sold in 220 countries in 77 languages. The seven books were adapted into eight Warner Bros. feature films, which grossed over $4 billion worldwide.

It would be hard to pinpoint who is the most devoted Harry Potter fan, but it just might be a man in Mexico City whose collection of Harry Potter memorabilia has been lauded the largest in the world by the Guinness World Records on Monday. The Associated Press reports that Menahem Asher Silva Vargas has spent 15 years forming his collection, which takes up two rooms, which now has 3,097 pieces. The old Guinness World Record for the largest Harry Potter memorabilia collection was 807 pieces.

"My salary, my bonuses ... it all ended up here," said Silva Vargas, a lawyer by profession, to the Associated Press, adding that he never intended to break any records when he first started his collection. That being said, Silva Vargas is definitely devoted to the wizard world and we think it's time he received an invitation for Hogwarts.
