Donald Duck & Co #10/1965

In "Å, du gamle tiøringen min!", Scrooge and Donald dive into the deep sea in a bathysphere to recover Scrooge's lost treasure—the sunken ocean liner Old Number One Dime—only to discover it's not alone. Beneath the waves lies a vast undersea shipyard run by four-armed Martians, who are salvaging iron from sunken ships for their own planet. With Donald's latest job as a news-hungry reporter complicating matters, the search for the dime takes an unexpected turn into the unknown.
