Bookmarks: trying to decide if bigger is better.

I’m designing bookmarks for Demon Night, and am wondering: for those of you who use/collect them, do you prefer bookmarks that are slightly longer than the book, so they stick up a little — or that can be tucked inside, so that when they sit on the shelf, it disappears into the book.

And, just general design question — smaller cover pic with border, or larger pic with sides cut off and only a border on the top/bottom? (Ignore the text for now — I’m just seeing what fits — the larger pic allows less text/quotes … but is that good or bad?)

I can’t decide. But voting is always good. (see pics after jump)

And this is what the back will look like, but it probably won’t change:
