In the beer v. milk example, the difference between the two liquids is evident upon visual observation. Thus, the sign becomes irrelevant. By analogy, Iron Monger is the glass, and Obie is the liquid. Here, we do not know what's inside. The difference between a full figure and a torso cannot be discerned by visual obervation. Therefore, the sign becomes critical. We must rely upon the representation of HT because they know what's inside. We do not.
YOur argument makes some good points but fails in one MAJOR regard. You are ignoring the laws of physics with regards to how a 12 inch action figure could ACTUALLY be inserted into the iron monger when a real man could not fit in the actual movie prop.
