This is the cover for Detective Comics #844, drawn by Dustin Nguyen.
For my birthday, my wife had me pick out my favorite Batman cover, without knowing what it was to be used for. After flipping through my back issues, this is the one I settled on. And now, I have a shirt with it on. I think what makes this cover one of my favorites is that I really like the Batman/Zatanna pairing. In the future, you can probably expect more of Dustin’s covers feature, as I really like his covers, though not as big a fan of his interiors.
