he described the famous photo of St. Paul's Cathedral surrounded by smoke in the Blitz as London flipping the bird at Hitler
I actually get that same impression from that photo of Winston Churchill making his "V" since all he would have to do is turn his hand around and he'd be giving Hitler the two-fingered salute.
The wall wasn't my favorite part of the IWM, but I was fascinated by it nonetheless. I'd have a hard time picking my favorite.
Back on topic, I do like the idea of an idealistic (and very mobile) Clark going to witness the collapse firsthand. That would make more sense that Lois since he would have been about 23/24 at the time.
