This beautiful ink rendition by Roy Krenkel is of course based on the original painting by PJ Monahan for Tarzan and the Golden Lion, for the December 9, 1922 cover of Argosy Magazine.
It is not a swipe, but pays honor to the classic illustrative history of ERB , as well to flex Krenkel's artistic muscle and 'improve' Tarzan's visual identity.
Above, Roy Krenkel. Below, PJ Monahan—1922
You can certainly see some of the inspiration for Frazetta, as well.
