From one of the Hartman Brothers (who founded BotCon, and now have the Hall of Fame award named after them), several BotCon items have recently been listed, including original pages of inked artwork for their 1997 comic (Ground Zero).
Their store page can be found here for other BotCon items, but these are links to some of the comic pages:

If you are interested in buying - Note that they are on poster board, so would be have to be mailed out in a large (expensive) mailer.This is the original pencil and ink artwork of... the BotCon 1997 comic, "Ground Zero." The comic was pencilled and inked by veteran Transformers artist Andrew Wildman, and was the first licensed comic in the Beast Wars universe. The artwork measures 11-5/8" x 16-1/2" and is on good-quality poster board. The inset image in the bottom left corner shows how the final rendering of the page looked in the comic, and is not present on the actual item you will receive.
For the rest of us, this might be the only time we'll see this original artwork before it is sold.
