The display, in relation to the figure in the pictures, looks like it would be a really tight fit on a standard card. Ephant Mon weighs as much as a pound of roast beef, but he's compact.
Even so, barechested Darth Maul and Amanaman, both of which can be seeen at all TRUs that I go to for $4.98 on clearance, were hardly deluxe figures to start with as well.
But if push came to shove, I'd pay it for Riekken. He's too cool to pass up.
