My story takes place between the 20s and 30s (I would even sai mid 20s end 20s). It takes place in new jersey, most of the time in new york. I have a lot of fun during my reserches and learn a lot about American culture (I'm French ^^ ).
I took a lot of time to watch old films that have some good reference about the clothes and living style. I also read a lot of diverse articles, even old news-papers articles if i found some, it gave me a good idea how people where thinking back then.
I also learned a lot about medecine of this time, some things really made me have shill.
There are sometimes things that are hard to find, but most of the time i'm capable to adapt and try to stay as close to facts then i can.
And last thing, it's a mafia story \o/
So, if one of you also do a story during that time and struggle finding something, don't hesitate to contact me, i would be glad to help and share information and references
