Going through some old files, I found this interesting artifact -- eight sheets of what looked like scratch paper clipped together, with my loosely-scrawled rough layouts and dialogue for my Usagi Yojimbo and Leonardo crossover short. It's been a while since I have read the finished piece, but I think it pretty closely followed these roughs.

According to the folks at the very cool Usagi Yojimbo fan site (http://www.usagiyojimbo.com/), the issue of UY with this story is still available from Fanatgraphics.
