Letter from the bilges:
Dear Onkel Karl,
I can't find that nice, shiny U-Boat you gave me. To remain a member in good standing in the 2ndPYAD Club, I need another type IX sumbie. Please send one to Lorient ASAP. Bernard asks if you could include a pair of teddy bear pajamas and bunny slippers.
Eagerly awaiting to go on patrol again
