As part of next year's celebration of Batman's 75th anniversary, DC Comics recently announced that the upcoming Detective Comics #27, the original version of which featured the first appearance of the Dark Knight in 1939, would include contributions from several notable creators, including Frank Miller. And on Tuesday, the publisher revealed Miller's cover for the issue which, it turns out, is not actually a new piece of art.

The image above is of Catwoman (who actually didn't make her first appearance until Batman #1 in 1940), but it was not created specifically for this issue. As pointed out by Rocket Girl writer Brandon Montclare, the piece was illustrated during Miller's run on his and Jim Lee's All-Star Batman and Robin, a series which Montclare was one of the editors on.

Of course, using an image created years ago for a cover is a normal and perfectly reasonable practice in comics. Artists create a lot of work which sadly never sees the light of day. And besides, if you haven't seen it, it's new to you.

But like Montclare, we can't help but wonder where the hell that tail is attached.
