Patriotic Mobsters

Kestrell and I recently watched "All Through The Night", a comedy-drama with gangsters versus Nazi spies, released mere weeks before Pearl Harbor. It's not the *first* movie I've seen that had the trope "We may be crooks, but we're *American* crooks!" … But I wonder whether or not it's the *earliest* appearance of that trope.

Anyone have other examples? I know I've seen this before, but it's apparently not common enough to get a TVtropes entry.
