Vintage 1930's-40's Glass Salt and Pepper Shakers

We found these at a flea market. It took a while to figure out what they were but luckily there were patent numbers on the bottom. They are a set of Salt and Pepper Shakers and a holder invented by Stanley J Beebe of Norfolk Virginia. The Shakers were invented in 1933. They are glass jars with screw on caps. Attached to the cap is a plastic like tube that the salt and pepper come out through. There is a risque picture of a waitress applied on it. In the front she is fully clothed, from behind it is quite risque for time. The holder is metal and was invented in 1942. I cant find anything like them anywhere They are so cool.
