KISS and Manowar
Here is Manowar-Fighting the world from 1987.
Both were done by fantasy artist Ken Kelly. So my question is was the Manowar cover done just because they wanted to be like KISS or was Kelly running out of ideas so he "borrowed" from his previous work? I have no idea. Maybe it doesn't matter. Both have a high cheese content, but the KISS cover works better for me. To me their cover says "we are goofy and over the top, but we know it". While Manowar's cover seems to be saying "we are very manly men even though we have long hair, shaved chests and custom made leather outfits". I guess it's all in the eye of the beholder though.
