Thank you! Some years ago I saw a textbook like book from the 1920's/30's, I think, that taught shorthand. I took a peek at some of the inner pages and kept thinking to myself, why would anybody want to learn all this gibberish? It looked really complicated. I don't remember if the book was for a secretarial school, or what. But it was very complicated to my eyes. Anyway, not sure why someone would write shorthand on a postcard unless they were trying to conceal something from USPS...
