The Power Boys Adventures are a series of six juvenile novels published from 1964 through 1967 by the Whitman Publishing Company in illustrated hardcovers without dust jackets. They were written by Mel Lyle and illustrated by Raymond Burns. The books feature the adventures of two teenage brothers, Jack and Chip Power, who live and travel with their photojournalist father Thomas Power. During their travels, the boys get involved in a number of exciting adventures in which they solve mysteries and track down criminals. Their six adventures in chronological order are: The Mystery of the Haunted Skyscraper, The Mystery of the Flying Skeleton, The Mystery of the Burning Ocean, The Mystery of the Million-Dollar Penny, The Mystery of the Double Kidnapping, and the The Mystery of the Vanishing Lady. ABOUT WHITMAN BINDINGS OF POWER BOYS BOOKS: In the early 1960s, the books were published in illustrated hardcovers with a laminated coating. These were attractive books but were easily damaged. In the mid-1960s, a stronger matte-finish cover was introduced. These books did become worn or damaged but held up better than their predecessors. In the early 1970s, Whitman changed the size of its juvenile line, reducing the width of its books by one-half inch. The height remained the same, so the change was not noticeable when books were lined up on a shelf. Power Boys books can be found in all three variations.
