WESTERN popular culture had a significant influence on the father and even ”God” of modern manga, Osamu Tezuka (1928-1989). Sometimes he let it show clearly in his works.
The most obvious examples are the graphic novels Banbi (1951) and Pinokio (1952), where Tezuka directly used characters from Walt Disney’s movies Bambi and Pinocchio. Now I will show a set of lesser examples.

The manga Saboten-kun (1953) is set in the Wild West. One of it's western guests is the American actor Ernest Borgnine.

Saboten-kun's mother is quite a lot like the mother of the Katzenjammer Kids, by Rudolph Dirks and Harold H. Knerr. By the way, the same model was probably used by the Finnish artist Ola Fogelberg in his comic Pekka Puupää ("Peter Blockhead") to create Pekka's wife Justiina.
