Some books, well, the newer once, have
pictures from the movies on the cover.
Is those books any different compared to the "original" once
with the old covers?
Or is it the same?
They're different, of course. But even the "originals" vary. I myself have seen at least three different kinds of cover art for the LOTR books before the movies came out. I have no idea which is the most original one. I suspect it's the one with Tolkien's own artwork on it, though.
