Similar to Val-Saint-Lambert in Liège and Scailmont in Manage, the glassworks Doyen in Havré are among the jewels of internationally renowned Belgian glassware in 1930. This 'Yvette' service is hand-carved, on the wheel, 'size mate 126' (see catalogue 1935). In mint condition (the bubbles and the few differences are due to the manufacturing process, no hairline crack, no chipping). A 'cristallin' label indicates half crystal.
