Ralf,
You continue to create a really wonderful theme from a period that Playmobil has pretty much ignored
I made an earlier comment about this historical era and how it affected those years between the two World Wars and the time of "prohibition" in America.
In the United States the gangsters had become the anti-heroes. They (and their "ladies") wore many of the costumes in your theme.
NOTE: When Mattel had the license from Playmobil, they created some police sets that could be easily converted into Chicago cops.
Attached a photo of the famous eight corner police officer's cap (from Mattel/Playmobil) that was worn around this time.
Ralf, Thanks for sharing your fantastic imagination with us.
Richard
