I'm pretty sure Soundblaster doesn't actually have one, Griffin. (I'd be worried if he had a crazy-huge G.I. Joe collection on top of his already insanely amazing Transformers one.) The ones in his original pictures are from the Sears Wish Book (from the X-Entertainment site): http://www.x-entertainment.com/articles/0969/
and the one I think you thought was Soundbalster's is from the brother of the person who writes this blog: http://jananetty.wordpress.com/2009/02/13/the-latest/
