After my series on the Japanese Fu-Go fire balloons of World War II, a reader forwarded this cartoon, which appeared in the Chicago Tribune on August 8, 1945, about three months after the fatal Oregon attack.  It appears to be warning kids to stay away from unexploded bombs.  And while it doesn’t match exactly, the last panel sure looks to be bombs mounted on a balloon, complete with Japanese lettering on the side of the bombs.

Thank you to Ed Maurus for sharing this!
