From the publisher's homepage:
Downloadable PDF-game of the golden days of the American Gangster. Found your own mob and build an empire of crime in the spirit of Al Capone or Lucky Luciano!
The PDF-layout is arranged so that all you need to do is to print it out, two pages per paper, stack them and put staples through the middle. When you fold it, you'll have a neat A5-sized booklet.
