Forbidden Worlds #71 (1958)

Arthur Lansing, a timid and overlooked clerk, stumbles upon the mysterious Mirror of Mowgaladi, which begins showing him harrowing visions of real dangers—first a blizzard where a man with a walrus mustache perishes, then a lion loose in Central Park—each time forcing him to act before disaster strikes. Though he struggles to convince others, the mirror’s eerie foresight proves terrifyingly accurate, leaving him both shaken and strangely grateful. As he grapples with the mirror’s power, Arthur begins to wonder if it might do more than warn—could it truly change his life?
