Superman's Pal, Jimmy Olsen #89

Jimmy Olsen goes full secret agent in this 1965 DC romp, with cover art by Curt Swan and George Klein depicting a green-suited Jimmy descending by parachute while firing a button flamethrower — much to a wide-eyed Superman's alarm. The cover even helpfully catalogs Jimmy's spy gadgetry, including a flashlight parachute-ejector, lapel laser beam, siren ring, and secret weapon, leaning gleefully into the mid-60s spy craze. Writer Jerry Siegel and artist Kurt Schaffenberger bring their talents to the interior, making this an irresistible slice of Silver Age fun.
