Last week, rejected logo designs for Marvel Studios' "Iron Man" made their way online, offering fans of the franchise a look behind the curtain of what goes into the branding of a major motion picture. Now, graphic designer Tom Muller's concepts for Marvel Comics' 2008 "Invincible Iron Man" logo treatment have surfaced.

The logos are described by Muller on his now-defunct website as "Redesign concepts... commissioned by Marvel Comics. The logo had to be based on the existing movie franchise branding and fit within a larger marketing and publicity structure."

Check out the logos below, and take a look at Marvel's early "Iron Man" movie logo concepts here!
