KEI once evidently had a 1280-sized wallpaper version of this great piece of work on his site (see here: http://kei-garou.net/blog/archives/2007/02/2p_3.html), but the link doesn't work anymore.

I know it's a long shot, but does anyone have it by any chance?

1. It's already available on danbooru: post #165069

2. I also managed to track it down via the Internet Archive Wayback Machine:

A lot of "lost" stuff you can be found there, especially if the artist is as popular as Kei.

Durr, I didn't even think of searching on here for the artist. Thanks!
