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 drunck 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.
This is one of the objects that was specifically made for Jewish use. This is an example of Bezalel work from the time of the 1920's in shape that is quite unusual. The material is brass with patina. The contrasting brass medalion carrying the image of the spies carring the grapes, without patina, is applied to the fluted cup.
Inscription: Bezalel Yerushalem
