Spidey Artist Screws Up The Web Shoot

Marvel Super Heroes #14: in 1968, Spider-man artist John Romita sprained his wrist. So they commissioned Ross Andru to sub. Luckily, Romita was still able to make his deadline. So ASM never missed a beat. But, they had the extra issue that Andru drew. So they put it in Marvel Super-Heroes #14. Trouble is, Andru seems to have forgotten how to draw Spidey's web shoot. Look at his hands. He's supposed to be pressing a button in the palm of his hand with his middle finger(s). True Spidey aficionados will see the glaring mistake in the palms.
