After the heavily cartoon- and slapstick cinema-inspired first adventures, Morris turned towards the
tradition of Westerns to flesh out his hero's world. In Under a Western Sky, Lucky Luke versus Pat Poker and Outlaws there is a lot of Hollywood and John Ford, and while Luke hasn't quite settled into his current look, he's certainly closer to the phlegmatic cowboy we know and love. Outlaws also marks the first appearance of the Daltons; the historical Dalton brothers here, who will later return as their decidedly stupider cousins. Throw in 48 pages of extra material on Morris's experience in the United States, and this is a book you won't want to miss.
