Lucky Luke - Volume 76 - Oklahoma Jim

Kid Luck, still travelling with Old Timer, arrives in Mushroom City.
After months in the wild, they’re both glad to find a place where
they can have some fun! While the old gold miner has every intention
to enjoy himself, though, he immediately sends Luke … straight to
school! A horrible sentence for the young cowboy-in-the-making, who
is about to meet a quartet of already nasty little brats, and a
pistolero with somewhat … flexible morals!
