"Four Pillars of Freedom" and "Our Four Great Faiths" ad campaigns
The T&P began their "Our Four Great Faiths" ad campaign in October, 1952. This campaign grew out of the previous "Four Pillars of Freedom" campaign - see my Print Resources page for examples of the booklets the railroad distributed with these campaigns.
Here are examples of ads from both campaigns:
Saturday Evening Post - Nov. 15, 1952 >
< Satuday Evening Post - August 4, 1953
< "Unless the Lord build the house..." Saturday Evening Post, March 29, 1952
"The Good Book is still Good for Americans!" > U.S. News and World Report, Sept. 16, 1955
