A refined and rare rectangular high-relief ceramic plaque from the 1950s, depicting the Virgin Mary in prayer. The work was handcrafted by the renowned avant-garde San Polo factory in Venice, based on a design by master sculptor and painter Otello Rosa (1920-2007). The piece stands out for its strong plasticity and splendid, thick polychrome work. The shiny robe and cloak feature intense shades of blue and turquoise, while the edge and large halo are finished with precious pure gold details, masterfully applied using the triple firing technique (third firing). On the back, perfectly legible on the dark enamel featuring the classic crackle effect of the period, are the original hand-painted trademarks: Manufacturer name: "San Polo" Origin: "Made in Italy" Serial/Model code: "2/59" Dimensions and weight: Height: 33 cm Width: 13.5 cm Thickness: 2 cm Weight: 1,129 grams Item condition: The structure of the plaque is perfectly intact, with no cracks or repairs. The pure gold and enamels maintain an excellent brilliance. There is only one cosmetic defect on the Virgin's face, with some superficial enamel falling away on the cheek and forehead (as clearly shown in the detailed photos). A historic and extremely expressive piece, perfect for collectors of 20th-century Italian ceramics.
