I have 4 matching salt and pepper shakers by Poole. "ASTOR SHAKER SET REG. PAT. APPLD. FOR BY POOLE., 567 E." T is also a mark of a face with hat (could be a jester?). They are 5-1/4 inches tall. Beautiful Art Deco style. Very nice condition. They do need to be polished. I purchased them from the estate of a family friend. She is in her mid 80's. I think the shakers are probably from the 1920's or 1930's.
I received a nice note letting me know that the mark is a Quaker woman in a bonnet. Thanks
