Each glass reflects traditional craftsmanship, with slight variations that confirm their handmade origin. The clarity of the crystal and the sharpness of the cutting highlight the quality associated with Belgian glassmaking from the Boom region, historically known for its production along the Rupel river. Importantly, the glasses retain their original factory labels, a valuable detail that supports and confirms their authenticity. A decorative and collectible set, perfect for Art Deco enthusiasts or for elevating any table setting with timeless sophistication. Condition: excellent vintage condition, no chips or cracks. Capacity: approx. 110 ml per glass. De Rupel glassworks, established in 1925 in Boom, Belgium—a town nestled between Brussels and Antwerp—initially specialized in producing mold-blown beer glasses, including the iconic Duvel glass. In 1935, the company appointed Paul Heller as chief designer, who introduced decorative glassware to their repertoire. By 1936, De Rupel was renowned for its distinctive black vases adorned with hand-painted floral and architectural motifs. The factory also produced various glassware lines, such as Artver, Artlux, Boom, and Arlecchino, encompassing vases, stemware, lampshades, and vanity sets. Despite their success, De Rupel ceased operations in 1971.  Will be well packaged, protected and insured
