covered up in bait-and-switch

I know... well, I strongly suspect... that this cover is supposed to be funny and I get the joke. It's just not a funny joke.

The solicited cover may be a little bit flat, but it screams "old school Batgirl". You know that whatever Batgirl was when she started, this was it. Apparently this is the cover for her first appearance, which seems quite fitting for the volume of her first comics.

What the cover it actually got screams is a little bit different. It is more along the lines of "heroine not worth reading about". I'm not certain how that is supposed to sell books.
