"A Refresher Course in Gregg Shorthand"

I was just perusing eBay and saw this book - A Refresher Course in Gregg Shorthand" by John Robert Gregg offered for sale.   I am not going to buy it - they are asking $40.

But I'm curious.  I had not seen this book before.  It says that it is copyright 1942 and printed in 1945, so it must be Anniversary edition.

The title seems self-evident, but there was no table of contents shown nor any pages... just the book cover.

Is this a summary of Anniversary principles?   Does it have reading and writing exercises in it that aren't found elsewhere?

As always.... I am curious :-)   At a much lower price, I probably would have ordered it -sight unseen... but not at $40.....
