I was so pleased with the wonderful drawing that I had commissioned from Tracy Reynolds at Rainfurrest '09 (you can see it here: http://www.furaffinity.net/view/2826571 ) that it wasn't until the next day that I showed the picture off to someone-- and noticed this sketch on the back!

I assume Tracy Reynolds drew it, but she did tell me she had gotten help from the artist sitting next to her. I don't recall the artist's name, but maybe he drew this for her as a reference?
