Watching The First Avenger for the first time in a while, I can't help but suspect the blonde that goes, "Hi" during the war bonds sequence; in light of She-Hulk's recent end-cap comment about his time with the USO.

I also can't help but think about the classic style shield fitting into the story. Just how much would a guy have to be tossing that thing around between shows to end up carting it along on his daring rescue mission. That, and that in context it would have likely been a slab of wood. The only reason I can imagine it being made of metal, as seen when Red Skull punches an indent in it, is consideration for the Italian campaign being far more at risk than state side.

I.e., I have a rather hard time imagining someone making such a fine metal "Stage prop" given the extent of war time rationing and prioritization. The only thing I can imagine is someone deciding, "Yeah, if artillery shells start bursting or something, let's try and avoid shrapnel going through it like a hot knife through butter." Somehow, I doubt Roger's would have appreciated that treatment.
