One of Simon and Kirby's most entertaining creations is Stuntman. While he didn't end up being much of a financial success for Harvey Comics when the duo launched him alongside Boy Explorers after the WWII boom, nonetheless the art and story Joe and Jack produced for this quixotic and amiable character was top notch. Here is a rendition of the character by the 'King" with Jim Steranko supplying the inks. (Of course Steranko was oddly an influence on Kirby when he created Mister Miracle for DC as part of the Fourth World saga.)
Here is that same image minus the Steranko embellishment, just in raw Kirby form.
