I know it looks like Wally Wood art. In fact, former CRACKED editor Mort Todd tells me it's often misidentified as Wood. But if you look close, you can see Morrow in some of the faces. Also, Morrow is credited in this issue while Wood was still busily working away as the main MAD artist at the time! Could he have assisted Gray on a deadline? Maybe. Could be. More likely a Morrow homage to Wood, though.
