A rare 'taille Canadienne' Val ST Lambert four colour bowl c.1925

A rare 'taille Canadienne' Val ST Lambert four colour bowl Belgium c.1925 Designed and made by Joseph Simon the pre WW2 head of design for Val St Lambert The glass is made in three layers, clear, yellow and amethyst, there is also a rim of red glass which is unusual. The glass is then cut from both sides a skill I believe now lost as the success rate would be very low.
