A very well written sourcebook full of ideas. Although written for GURPS it can be used for any other system. It contains a time line of thirties, a seizable geographical sections dealing with possible adventure ideas for a given country, there is of course an equipment table, templates of adventurers, chock-full of scenario seeds, a section on scenario design and creation of memorable villains and more. Altogether an excellent supplement for GM. It has characteristic GURPSy "dryness" - i.e. no fluff and no imposed ideas. It is a toolkit for people who want to develop their own ideas. Big thumbs up!
