You have got to check this out! Woah. Don Figueroa posted some of his original art on the 2005 message boards. This, "rejected concept art" includes GI Joe vs. TF crossover and another original story Don pitched. Very cool stuff.

Also, from the "what could have been" files! Check out this unpublished Alex Milne art from unpublished TF: Energon, brought to us courtesy of Cybertron.ca. Thanks to allspark for the heads up, TOO cool...
