This cel is from the treasure hunt in episode 19. The detectives have found something precious, after all....
Did I mention this cel is huge? I mean, really, really, huge? It was used in a long pan shot going diagonally from i Suoh to Nagisa. I've picked the center of that pan for the screencapture. I finally got around to scanning this cel myself (until now I'd been using the scan kindly offered to me by the dealer). Because it's square and scanners are rectangular it took six pieces, so there may be some alignment problems. ^^;
I really love this cel!
