Cover artist Martin Naydel is mostly known for his funny animal work, but for a short while he contributed to the covers and introductory chapters of All-Star Comics. His terrific cover is reproduced as the splash page inside. The story is written by Gardner Fox. Some feel that the title bears a deliberate resemblance to the Alfred Hitchcock film The Man Who Knew Too Much. The pages are off-white. The book is CGC-certified 8.5 (VF+). According to the CG Census, this unrestored copy is tied with one other as the third-highest graded copy they have seen. It is also recognized as being part of the “D” Copy Pedigree.
