Leo Baxendale is often credited for work in Smash! but he no longer worked on the title after the initial opening issues. He returned to Smash! when IPC revamped the title.
Although Smash! regularly featured Hulk comic strip reprints this story was originally published in The Fantastic Four. The purpose was to entice readers to buy Wham! which featured the Fantastic Four comic strip every week.
