Pulp Avengers: Game Mastering in the 1930s and 1940s

The Dick Tracy Pulp Era Role Playing Game
The Dick Tracy RPG brings the classic comic book detective to life. When I was a kid, my dentist had a couple of books with Chester Gould’s complete Dick Tracy strips, and I used to look forward to going to the dentist twice a year so I could read them.
In this RPG system you create characters eight attributes, skills and advantages / disadvantages. Action is resolved with a 2d6+attribute+skill versus difficulty system. Tasks are rated according to a five point difficulty level. The system also has stats for characters such as BB Eyes, Breathless Mahoney, Flattop, and of course, Dick Tracy.
I’ve often thought that these wonderful characters would make great miniatures.
