I stumbled onto these gems while looking for Iron Man stuff. These two drawings are found on a blog that calls itself: “Tony Stark: Your GO TO GUY! – Featuring doodles and drawings of everyone’s favourite transistor-powered superhero: TONY STARK — THE INVINCIBLE IRON MAN!“. The two cutest versions of Iron Man and War Machine were drawn by Jason Quinones, who describes these drawings as more of an “Iron Boy.” No matter what, these are cool, and I wish I could buy a print.
