Set of 6 coloured vintage glasses - glassware from Boussu

Set of 6 coloured glass tumbler-type glasses (series of 6 colours known as "harlequin"), series "Karin", created by Zéphire Busine for the glassworks of Boussu in the early 1960s. They are in very good condition, with no noticeable damage, except for one with a chip on the upper rim. However, there are bubbles and small differences between the glasses, which is quite normal for mouth-blown glass. Dimensions: Diameter: 7.5cm, height: 10cm.
