What I can tell you though is that Contact, Dropise and a Life Force are often grouped together as The Contract With God trilogy, so there is some thematic overlap and all are drawn form Eisner's experiences in NYC, but I don't know if there is any iverlap with plot and/or characters.
No overlap of characters; it's the neighborhood that connects the stories.
I'll likely still be in the middle of Le Cri du peuple so if, as I expect, I'm too far from the end to finish it within that week maybe I'll try to slip in something else that's shorter. I have lots of stuff here that I haven't read so it'll probably come down to whatever I happen to be in the mood for at the time.
Going to hit the library tomorrow and raid their Will Eisner section. They have pretty much every GN he ever published. I'm definitely going to pick up Dropsie Avenue and will see what else piques my interest. I've got my own copy of Contract with God at home, of course.
