This antique kiddush cup, also known as a becher, is used for reciting the kiddush blessing over wine on Shabbat and holidays. It measures approximately 2.5 inches (6.35 cm) in height, with a diameter of about 1.75 inches (4.45 cm) at the rim, tapering slightly toward the base. Weighing 34 grams, it is lightweight yet sturdy.

The body features a cylindrical form with a delicately beaded border near the rim. The side is adorned with a shield-shaped cartouche engraved with the intertwined Hebrew letters "א" (Aleph) and "ר" (Resh), likely the initials of the original owner. The cartouche is framed by ornate chased foliate motifs resembling feathers or leaves, typical of Polish Judaica craftsmanship during the interwar and post-war eras.

The base bears two hallmarks:

• The assay mark: a lozenge-shaped stamp with the number "3" to the left of a woman's head in profile facing left. This is the Polish state hallmark for 800/1000 silver fineness, used from 1931-1963, often indicating Warsaw origin (though no explicit city letter "W" is visible in the provided images).

• The maker's mark: "K.M" (in Latin letters). This mark belongs to an unidentified Polish silversmith active during this period, likely operating in Warsaw. Historical records of Polish silver makers from 1931-1963 show similar initial-based marks for small workshops specializing in Judaica, but no definitive attribution to a specific individual. Such unidentified marks are common for minor artisans in Eastern European silver production.

This piece reflects the enduring tradition of Polish Jewish silversmithing during a challenging historical period, including the interwar years and post-World War II reconstruction, when Warsaw was a center for Judaica items.
