The Amazing Spider-Man #183

The Big Wheel — a massive, riveted, rolling mechanical monstrosity — dominates this August 1978 cover as Rocket Racer and a battered Spider-Man scramble to contend with it, the boastful cover blurb taunting that not even Rocket Racer can stop this unstoppable threat. Ross Andru's pencils and Ernie Chan's inks bring tremendous kinetic energy to the city street scene, with explosions erupting at Spider-Man's feet and the enormous wheel bearing down on both heroes. It's a wonderfully off-the-wall late-'70s Marvel cover that delivers exactly the kind of over-the-top danger the story title promises.
