In processing the Mail Order patterns, I've seen this particular story repeat many times. I thought I'd take a couple minutes and share it with you. The centerpiece of the story ....
This particular story takes us back to 1939. Every couple days in newspapers across the country, an advertisement for a pattern would be printed in the women's section. The advertisement were written to resemble an article, a woman' feature.
Such as this article, which appeared in the Denver, CO paper on June 8, 1939. Miss Doris Biggar, read the ad, and decided to purchase the pattern. She mailed her letter, along with 10 cents to the newspaper's department. On the bottom of the pattern clipping, she wrote in the date she mailed for the pattern. (I frequently find this in the Mail Order patterns - the pattern and clipping inside the original mailing envelope).
A couple weeks go by, and the pattern is returned. (Note, the envelope reads mailed from the Denver Post, however, the Post Office stamp reads San Francisco).
