Second, central panel is amazing use of facial expression, it had a lot of impact.
Thirdly, the last panel had the most impact for me, seeing Frankie with his military hair, smiling in ante-bellum innocence, still so Frankie, but still so far from the Frankie that will come out of the Argonne in a year and a half's time.
Centre panel. Just... centre panel. It's like the living proof no one wanted that sometimes you don't even need to travel to 1917 France to get shell-shocked. Also, I'm bowing to your henscratching and, later when it's less hot, building an altar to it and sacrificing a pidgeon.
It's summer for you. That time of the year when Germans on vacation come to crowd our beaches, and I come in peace to bother them with my horrible spoken German. (For the record, there's also a thriving colony of French people, but speaking THAT language is safely out of my league.)
