What's wrong with this cover?

Look closely...
Figure it out?
Clue: One of those Avengers (as shown) doesn't belong there...
Ready for the answer?
Iron Man!
"But..." you say, "Iron Man was one of the original Avengers!"
Quite correct!
But...the all-gold armor Iron Man never appeared with Captain America!
By Avengers #4, when Cap was defrosted, Iron Man was wearing his first red-and-gold armor...

...so this particular assemblage of Avengers, as shown, never occurred!
You could say the cover is "symbolic", but shouldn't "accurate" transcend "symbolic", especially when it's easy to do and would look equally-dramatic?
(The red-and-gold armor was less-bulky and looked kooler!)
Yeah, it's nit-picking, but I expect better from "professionals" who are paid to "get it right".
Hell, it's what I did when I was working full-time in the business...
