I like how the final scene

is a wink at the 1943 painting by Adolf Reich, "Das grossere Opfer" (The Greater Sacrifice) :

Biki: Good catch! For anyone curious the original painting is set in front of the Siegestor (Victory Gate) in Munich, which was heavily damaged in WWII and was restored with a new inscription Dem Sieg geweiht, vom Krieg zerstört, zum Frieden mahnend translating as "Dedicated to victory, destroyed by war, urging peace"
