Saucer for a Teacup, from the "Borromeo tea and coffee set"

On all the pieces of the set are repeated the mark, the italic A, standing for King Augustus III of Poland (1696 -1763), and the arms of the Borromeo family. The latter, set in the decoration, have the form of a shield, with “Humilitas” inscribed on it, and a unicorn and a snake on the left, a dromedary on the right. Below it hangs a star-shaped emblem, identified as the Polish Order of the White Eagle. A document shows that on November 19, 1736, King Augustus III of Poland signed the investiture of Federico VI Borromeo (1703-1779) in this order. It is possible that Federico either commissioned the service or received it as a gift from the king.
This work is very valuable for the refined decoration with its “port scenes” and its excellent state of preservation, which is due largely to its case: a fine wooden box lined with green velvet with tapes and silver hinges and locks.
