Ken Reid's World Wide Weirdies and its sister series' Creepy Creations and Wanted Posters ran for years in IPC's Whoopee! and, before that, Shiver and Shake (Creepy Creations came first, in Shiver & Shake). Usually displayed in colour on the back cover, they are among the most striking images to have appeared in those titles. They were based on ideas submitted by readers, with anyone whose idea was used winning a cash prize!
