It's like someone
took a slice of Deadwood and put it on wheels. Wish I could find more pics of the interior.
Actually, it also kind of reminds me of a sketch green_trilobite and his friend Jason Taniguchi wrote years ago, in which a writer tries to pitch his idea for a tv Western, which begins to sound oddly familiar:
RODDENBERRY: And the wagons, they're so high that the settlers need to use these long wooden beams to get down. They just climb on the beams and slide: Beeeeam down!
EXEC: Then how do they get back up?
RODDENBERRY: They just BEEEAM up! and there's this Black lady with a really loud voice! She's so loud she can shout messages to other wagons, and even other wagon trains! And so, her nickname is "Uheardme."
EXEC: "Uheardme?" (sighs.)
