Mobil Disney Comics #13

In "Ninety Day Wonder," Mickey volunteers to help Goofy clear out his attic, but a fall leads to a head injury that sends Goofy spiraling into a delusion—he’s convinced he’s his long-lost great uncle Jeremiah Van der Goof, a turn-of-the-century bare-knuckles champion. Over the course of ninety days, Goofy the Battler rises through the ranks, fighting his way toward a world championship bout. Jack Bradbury handles both the interior art and cover, bringing the whimsical transformation to life in this 1964 free comic from Mobil Oil Australia.
