Merry Christmas, everyone!
I was asked by Astro mega-fan Lisa to share this with everyone for Christmas, and I am happy to oblige. It's an illustration by Japanese artist named でんのく (Dennoku?), but an English translation and accompanying poem have also been added. A small version can be seen by clicking the image on the right. You can see it full size here, and it's a large file.
You can check out the artist's website here and see more Christmas cheer on the Astroboy-Online forums.
