Modern Business Correspondence (1907)

Continuing my last post about my business writing class, I found this book at the University of Utah's library sale. It was written in 1907 and has chapters about how to send Telegrams and Cablegrams, how to send a letter through the mail and how many hours it will take to arrive, and how to write a good advertisement as a merchant. It gives this poem for all merchants to remember:

"We may live without poetry, music, and art;

We may live without conscience and live without heart;

We may live without friends and live without fads-

But business today can not live without ads."

What I found quite funny was the politically incorrect way of writing toward women. check it out for yourself here.

So, if i understand correctly, all women should only be signing their own name if they are unmarried or widowed? When did that change?
