To mark the 20th anniversary of the publication of the first Harry Potter book here in the USA, Scholastic has decided to re-release the books with beautiful new illustrated covers. The new illustrations are by Caldecott Medal-winning illustrator Brian Selznick and I think they look really nice, though as someone who grew up with the original books, I think I prefer the original USA covers.
The covers all blend together to make one large Harry Potter mural. Entertainment Weekly stitched them all together and this is what it looks like (click the image to view a larger version):
To see the individual covers, check out the gallery below. These brand new editions will hit shelves in the U.S. on June 26th.
