Donald Duck & Co #37/1966

In "Gull under regnbuen," Donald and the boys set out with Scrooge’s blessing to find the fabled pot of gold at the end of a rainbow, their jet-plane search soon hijacked by Magica De Spell, who has her own plans for the treasure. When the rainbow leads them to a distant land where rain hasn’t fallen in a year, Magica summons a torrential downpour to create her own rainbow—raising the question: if the sky answers magic, does the legend still hold true?
