Subtitled 'World's Wackiest Facts,' this wacky card set continued Topps's success with illustrated card sets featuring juvenile humor.
The card fronts featured the series title along the top, with a full-color illustration below, setting up a gag by telling the story of a person or event... which was continued on the back with a concluding punchline. Card backs were printed in blue ink, with the card number in a black circle at the lower right.
Topps would have several successful card sets featuring this type of humor over three decades, culminating in the super-successful Wacky Packages mega-set during the early 1970's.
At least some of the artwork for this series was done by legendary comics artist Wally Wood.
