Here’s a fun thing to know:
Bill Griffith, who draws “Zippy the Pinhead,” turns out to be the great-grandson of William Henry Jackson, the Civil War -era photographer. And Jackson, in turn, was the great-great-nephew of Samuel Wilson – the man after whom “Uncle Sam” was named.
This, of course, makes Zippy himself the great-great-great-great-nephew-in-fiction-twice-removed of Uncle Sam himself.
This somehow explains a lot about America.
(Also: take a look at that image of Jackson…and then look at this shot of his great-grandson: definitely a family resemblance.)
