The 'Kosher Bread Stamp<nowiki/>' is an ancient stamp that dates back to the 5th century CE. Written in the paleo-Hebrew alphabet, it is part of a larger group of artifacts known as Canaanite and Aramaic seal inscriptions.
The Israel Antiquities Authority found the stamp during excavations at Horbat Uza.
The ceramic stamp is engraved with a seven-branched Temple menorah at its narrow base. A number of Greek letters and a dot are engraved around a circle and on the end of the handle.
The artifact was used to identify Kosher goods and likely belonged to a bakery that supplied Jewish people in Acre.
The name "Launtius" engraved on the handle of the stamp is likely the name of the baker.
