Save That Boy!

One thing in particular strikes me about this card, sent in 1943. It's the boy in the second row on the very left. His pants are pulled up high by suspenders. He looks like a skinny farm boy, who has fed the chickens, milked the cows, and is now being sent off to war. His family misses him already. I want to send him back home, but it's decades too late.
The message on this card reads:

This is what I looked like 4 months ago.

Love, Charles
