A fine Silesian engraved goblet and a cover Riesengebirge, first half 18th century

the flared bowl decorated with four panels enclosing allegories including one of friendship with inscriptions, flanked by putti, strapwork, birds on ledges, floral festoons, fruit and scrollwork, the base cut with facets over an hexagonal inverted baluster, the conical foot engraved with formal scroll, the pontil engraved with a monogram PVO(?) below a coronet, the associated domed cover with faceted finial
