* ValuesDissonance:
** In one of the early stories, Buck and Tumbler react to a (white) man Sonny [[BlackFace accidentally poured tar]] on with "Oh look, a negro!"
** A later one has a plantation owner addressing his workers as little better than dimwitted slaves. A footnote explains that this was the common practice at the time, so it may count as DeliberateValuesDissonance, especially as the plantation owner gets betrayed by one of his slaves and executed for helping the heroes.
** In an early comic, the heroes ally with a [=MI6=] female agent who proves to be very good with a gun. Buck then comments that, if she cooks as well as she shoots, she'll make her husband a happy man (and he clearly intends this as a compliment).
