Well, it now looks like this:
You can see roof, top glass, and pavement have been slightly "dirtied down."
Poster has a soldier with "We'll Meet Again...Buy More War Bonds" surrounding.
The handbill at front says "War Bond Rally...7 PM City Hall...Help our boys fight!"
Here's the other side:
"Kilroy" grafitti visible. The poster says "When you ride alone, you ride with Hitler...join a car-sharing club today!"
All done to a lovely accompaniment of Strauss on WABE: selections from Die Fledermaus and also "The Beautiful Blue Danube"—which, of course, I can't hear without thinking of Rudolf and Flavia dancing in The Prisoner of Zenda (the original, of course, with Ronald Colman...drool...).
I never could find a proper figure to go in the stair. I'll look again next year. I have a stray cat that can be placed outside.
