Here are some rare concepts done to promote Batman '89. I've seen a couple of these before.

I was always wondering - is this an official poster design, or fan art?

I've always loved these old posters. There's something nice about seeing something done primarily by hand as opposed to just Photoshop. I really like the the first one, as weird as it is.
