"Princess Pat Rouge is the World's most popular rouge, and rightly so - because it is made by the famous duo-tone process, an under tone and an overtone. This rouge really "does something" for you. It gives color that looks so real it seems your very own. Moisture proof too! Perspiration or swimming will not affect it. Princess Pat shades represent the height of fashion - created by leading fashion experts. For complete color harmony make-up that is most flattering, always wear Princess Pat Lip Stick and Face Powder with your Princess Pat Rouge." This is a vintage message princess pat cosmetics used to send out to there customers circa the 1940's. That is some awesome rouge if it stays on while you are swimming, imagine coming out of the water and having perfect rosy cheeks. I had trouble finding concrete facts about Princess Pat cosmetics, I did happen to stumble upon
the notes from a 1951 hearing of a lawsuit between Princess Pat cosmetics and another company, which answered quite a few of my questions. The judge asks the representative of Princess Pat cosmetics how long they have been in business and the answer about forty years. That means they must have been in business since around 1910. Another interesting question asked was who are some of your important customers and the answer," I would say Mar
shall Field, Mandel Brothers, Carson Pirie Scott & Company, Bloomingdale, Macey's, May Company, Walgreen, Whelan, Stineway Drug Company, Broadway Department Store, practically every worthwhile store in the United States and Canada, Simpson's Eaton's, Sanborn's in Mexico, and all over the world, practically." Princess Pat cosmetics were sold all over even though they made and shipped everything out of Chicago, Illinois. A study done in 1935 mentioned that Princess Pat dominated rouge sales at 10.2%, here are some PP vintage rouge tins and compacts I found in different stores online. Along with cosmetics PP also sold hair nets made of real human hair aswell as nylon nets. To go along with this post about vintage makeup here is a really interesting vintage article originally published in the 1940's it is titled Care Of The Skin And Its Disorders. 
This is the item that inspired this post on Princess Pat cosmetics, I just adore the color and the original card is so darling. This lipstick is unused and would be a wonderful addition to my collection but at $40 its not something I need at this moment. The back even had the stamp of approval from good housekeeping.
