The new look (of just the first book):
The old look:
Personally I love the new cover. Harry Potter is one of my favorite series of books and I am sentimental about the old covers; I will always remember them as the ones I grew up reading throughout the years. However, at the same time I am also really excited about the new covers. I think the artist did a fabulous job and I can't wait to see the rest of them. I already own the Harry Potter series, so I am unlikely to re-purchase the books just for the new covers. But I find them fun to look at and enjoy anyway.
What do you think?
