The children's publisher's hidden picture puzzle fold-out book expands to nearly 17 feet.

Highlights for Children Inc. got a rare honor Nov. 20 when it received a Guinness World Records title for its newest Hidden Pictures activity book, “Longest Hidden Pictures Puzzle Ever.” The fold-out book, which expands to 16 feet, 9 inches long, features 280 hidden objects that children (and parents) can search for and check off a list. The book’s 48 pages illustrate scenes of a relay race through a city. Highlights CEO Kent Johnson was presented with the award at the publisher’s Columbus headquarters. The company now holds the record for the “longest hidden picture puzzle fold-out book” ever published.
