Take a good long look at the photo of these special edition Harry Potter books. Can you spot the mistake? It's not easy, unless you are an absolute die-hard Harry Potter fan. A company recently had to reprint a special set of Hogwarts-house-themed books because fans realized something was wrong with one of the covers, Time reports

So what was the error? Each book cover in the new set features a house from the novels, including Gryffindor, Slytherin, Hufflepuff and Ravenclaw. According to the bookseller, Juniper Books, the Ravenclaw books feature the wrong mascot on the cover. The mascot isn't a raven, as featured on the blue book cover in the photo above—it's actually an eagle. 

'Our Ravenclaw design has a raven in it, and for the first time I've received complaints that [fans] wanted to see an eagle in it because that's the house mascot,' Juniper Books founder Thatcher Wine told Time. 

Fans actually noticed the mistake a little while ago, but it wasn't until very recently that Juniper Books caught wind. Apparently, fans began to contact Juniper Books after J.K. Rowling tweeted that Harry Potter's son was starting at Hogwarts

Here is the new cover of the book, with the correct mascot.

Wine said they would be contacting people who ordered the book recently to inform them about the new cover. He also disclosed which houses are the most popular right now. Gryffindor​ is their top seller, followed by Ravenclaw, Slytherin​ and then Hufflepuff. But he said the last place house is surging in popularity recently, because as everyone knows we are in the dawn of the age of Hufflepuff. 

So were you able to spot the error? Or did this one get by you like a wizard in an invisibility cloak?
