I believe I see the generic Charlton style of Bill Molno under three stories; the tier from "Swamp Gas" uses the man-at-the-steering-wheel shot I compared in stories signed by Molno and those Molno ghosted for Joe Shuster.
In the fourth Trapani-signed story the penciling style changes and reminds me of the scratchy effect in mid-seventies Charlton work by Bill Fraccio and Tony Tallarico. The clouds from the flying saucer in "Space Spiders?" show it most obviously.
