This is one of my favorite cels, ever. The cel is from OVA I. Alice is eavesdropping on a conversation between Issei and Jinpachi. Alice's eyes are haunting, and the flowe is a hand-painted masterpiece, done in cel paint and then retouched with water-based paints on top of the cel paint. This cel was used in the anime book (volume 1, page 24) though (oddly enough) it's reversed in the book (it was not reversed in the anime). Someone obviously flipped the film for the print by accident (or for effect).
