That’s Snuffy Smith, from the Barney Google comic strip! Steve recognized him!]
The strip was created in 1919 by Billy DeBeck, and he hired Fred Lasswell a few years later to do the lettering. It was Lasswell who created much of the hillbilly language that actually made its way into common American vernacular.
In his biography he says he “scoured used bookshops…for books on hill folklore.” He would note the language and use it in the strip.
