A Japanese map of the Pearl Harbor bombing that eventually brought the United States into World War II was auctioned off Friday with a hefty price tag.
The color map, hand drawn by Japan's lead pilot in the 1941 attack, was sold for $425,000 at Christie's.
The post-battle damage assessment map drawn in the weeks following the attack is titled "Top Secret" in Japanese.
It's 31 inches by 23 inches and includes English translations written in red by the same pilot.
The map was in the collection of Forbes magazine publisher Malcolm Forbes.
