I think it's Ron holding the sword and armour. (Armor? How the heck do we spell that over here?)
Literary Buffistas 3: Don't Parse the Blurb, Dear.
There's more to life than watching Buffy the Vampire Slayer! No. Really, there is! Honestly! Here's a place for Buffistas to come and discuss what it is they're reading, their favorite authors and poets. "Geez. Crack a book sometime."
I thought it looked like a house elf or a goblin on Harry's back, holding the sword.
And I think those are people, not gravestones on the US version. Look at the shapes closest to Voldemort, very head shaped.
SuziQ, you're right -- definitely a House Elf or Goblin but my guess would be House Elf.
I'm thinking house elf, myself - but am scared of Dobby.
Full version of the US cover.
(1) I think those are people (or souls if the curtain is The Curtain).
(2) I can't tell if Harry is wearing the Slytherin amulet/locket.
(3) Voldemort is TOTALLY doing "Stop! In the Name of Love!"
If you click on the picture to expand it (you get an annoying popup) but you can see that Harry is wearing the pendent/amulet/locket.
I did click on the picture to expand it, and I can tell that Harry is wearing something on a string/cord/chain around his neck, but there's not enough detail, even enlarged, to tell if it really is THE Slytherin piece o' jewelry.
Yeah, I'm not sure it's THE locket or not, but in conjunction with the locket on the UK adult cover, it's suggestive.
I wonder what all the broken stuff in front of Voldie and Harry is. It's going to be months before I can get my hands on this book, I know it.
What caught my eye:
(1) Harry and the cloaked figure (who isn't, or maybe isn't any longer, human) seem to be looking -- and more important, gesturing -- in the same direction. Which suggests that Harry and the cloaked figure are on the same side.
(B) The building in the background looks like Roman architecture. Possibly a coliseum?
