This is a Single Shaker in the shape of a Groom from the 1930s-40s and Sorcha Boru whose real name was Claire Stewart. She worked out of studios in Menlo Park and San Carlos, California in the 1930s thru 1950s. It is hand signed SBC on the base and has three holes and he does not have cork stopper. I have a collection myself and the lady who originally had alot of these knew her and went to the studio to buy frequently - some of the ones I am selling (and keeping) might be experimental or one of a kind - some pieces I have seen elsewhere and others not. He measures approx 4" tall x approx 2" wide at base and it in good pre-owned condition but has a glaze crazing - no chips or cracks. sale TERMS AND CONDITIONS: Please email me with any questions.
