Strange Adventures #154

In "Earth's Friendly Invader's!", Jim and Jill Tomkins are transported to the distant year 26930, where they encounter a mysterious, indestructible creature threatening the future. With help from their own time-traveling duplicates, they use their knowledge of Mark Twain’s A Connecticut Yankee in King Arthur's Court to outwit the threat, blending past wisdom with future peril. Written by Gardner Fox and illustrated by Sid Greene, with a striking cover by Gil Kane and Joe Giella, this 1963 Strange Adventures tale blends sci-fi adventure and literary cleverness in a rare, early exploration of time and legacy.
