I dug out my trade for you, Mxy.
Issues 1-4 were Sam Keith pencils, Mike Dringenberg inks.
Issue 5 is Sam Keith pencils,
Malcolm Jones inks
Issues 6-8 are Mike Dringenberg pencils/
Malcolm Jones inks.
The Sam Keith art, like Kelley Jones' art, is similarly Wrightsonesque
Especially nice and Wrightsoneque is Sam Keith's double-page spread of Hell and its crawling-dead minions in issue 4, pages 12 and 13.
Especially inked in a way that doesn't look like most of Sam Keith's other work, I can see them being mistaken for Kelley Jones.
But to answer your question, no, these early issues are
not Kelley Jones.
