I'm...not sure exactly what Steve is doing on that cover (lifting weights?), but otherwise should be good.
Seems like 50s Cap is going to be the first big story in the run not related to the Red Skull (Brubaker's done a great job making Cap's rogues work for the last 50+ issues, but it's all been so centred around the Skull, which is a common problem in Cap stories). If JMS was writing this I'd expect an anvilicious story about 50s Cap leading teabaggers, but Brubaker's pronounced his dislike for that kind of soapboxing with the character.
