American System of Dressmaking- updated

I had a lovely comment come through about a personal connection to the book (a relative who passed the course and gained their Diploma!)

The American system of dressmaking (1909)

So I have updated with a little more information to put the book in context. 

There are also a few more recent books that describe it as the largest successful dressmaking correspondence school at the time:

How I Learned The Secrets Of Success In Advertising
By Guy Lynn Sumner

And that lead to learning about Mary Brookes Picken as I realised I have probably skim read at least a few of her books through the archive.
