About 17 years ago, way before he ever dreamed up his highly enjoyable, crowdfunded Savage Sasquanaut, writer-color artist Wes Hartman teamed up with Gold Digger’s Fred Perry to unleash Sky Sharks. The five-issue adventure was told with a manga-ish flare in a dieselpunk style (like steampunk, but a different level of technology). For all its trappings, though, it was Hartman’s self-professed love letter to Dave Stevens’ Rocketeer.
