It seems as if the Trucking Industry figured out "Just in time" delivery long ago. Not too little - not too late - but all you need - when and where you need it.

This ad, like the one before it, references Bataan. Wikipedia:

The capture of the Philippine Islands was crucial to Japan's effort to control the Southwest Pacific, seize the resource-rich Dutch East Indies, and protect its Southeast Asia flank. It was the largest surrender in American and Filipino military history, and was the largest United States surrender since the Civil War's Battle of Harper's Ferry.

Ultimately, more than 60,000 Filipino and 15,000 American prisoners of war were forced into the infamous Bataan Death March.

But that wasn't known at the time of the ad.
