This old Lucky Luke album, that was published in 1955, is like a relic from the "pre-PC" media era, when you could have sinister swarthy villains - even "Jewy" villain characters, as long as you did not make it too explicit.
For it is hard for me to see the crook on this story, "Dr. Samuel Doxey," as anything but an implicitly anti-Semitic stereotype - a ruthless charlatan, a travelling medicine salesman who goes around the Wild West duping the gullible goyim:

But besides his looks and profession, what makes the "Jewiness" of this character especially clear to me is that he is not just a swindler, but an exceptionally
self-righteous swindler, who seems to have half-convinced himself that he is actually doing good to his victims - he manages to be cynical and sanctimonious at the same time, and has delusions of being a great humanitarian and philanthropist (like George Soros also does).
It is a gross mixture of sordid immorality and moral preening - like the rabbi owning "PornHub" company.
And oh yeah, he is
poisoning the waters of innocent people for his own profit:
