Here are a few of my art pieces as well as a poster I have in my collection.
Here is a pic of my signed J. Scott Campbell piece.
Here is my signed Sword Art Online piece signed by both ABEC (Sword Art Online's Illustrator) and also Reki Kawahara the writer of the light novel.
Here is a Naruto piece I have signed by Masashi Kishimoto.
Here's just a really cool massive Wolverine Vinyl poster I happen to have. That giant box next to it is a fully framed and linen backed Life size Ah My Goddess Belldandy poster from a extremely rare early 90's poster released by Kodansha.
