We used 1930s San Francisco as our main visual guide for the story, with locales ranging from provision shops to casinos, police stations to restaurants. A lot of visual reference was required, and aside from buying as many books of 1930s Chinatowns as I could get my hands on, there was of course the internet.
Below is a sample of the collated pictures! (Click on it for a slightly larger version)
See if you can match any of the images used to panels from the book!
(No prizes unfortunately, besides the quiet satisfaction of being just a little sastified :p)
Here meanwhile is another character sketch. Hank is on the lower tier, but who’s the old fellow with the moustache? Find out in… The Shadow Hero! :)
