Leica & Chrysler

New Leica is here - with interchangeable lenses and classic M39 screwmount.
Basic model is shown. It's the cheapest, of course, but in a year or two more complicated model with built-in rangefinder and expanded exposure range will prove to be much more popular among wealthy and demanding customers.
Chrysler building is only two years old.
It's 1932. Election year, btw
