The following description was prepared by William Gross:
The sanctification of the Shabbat and Holidays is connected with a blessing recited over wine or grape juice. While the wine can be drunk from any vessel, often special cups are created for the purpose. In most cases, regular cups are simply decorated or inscribed with names or blessings, rendering them exclusively for the Kiddush.
The typical Kiddush cup of the Hassidic Ruszhiner court is with a three-leaf base, a tree-trunk-like stem, and, usually, a covered beaker at the top. This example is missing the cover. The decoration engraved around the sides of the cup seems to have a relationship to other decorated items of a Hassidic nature utilizing the image of a unicorn.
