"Non-Conductor" from Plastic Man vol.1 #7 (Quality, 1947) by Jack Cole and Jack Spranger
A lot of the Quality Comics I've explored definitely have a penchant for humor, and perhaps that springs from Plastic Man's popularity. First appearing in Police Comics in 1941, he soon got his own quarterly dedicated series (in 1943) which eventually went monthly and lasted 64 issues, ending when Quality itself closed up shop and sold its assents to DC Comics. For a character initially stuck on another Earth, he got a better career than most. We'll see splashes from a couple more continuing series, and he even scored a Saturday morning cartoon! And yet, his tenuous position in continuity meant Elongated Man got his spot in the Justice League despite being the more original, more iconic, more "powerful" bendable hero. Morrison would finally set it right in his JLA, but it was a long wait!
