Beginning in the mid 1950's, the then-Czechoslovak glass industry began to participate in world exhibitions. Czechoslovak glass scored great successes, for instance, at these prestigious exhibitions: the Exhibition in Milano; Expo 1958 in Brussels; exhibitions in Sao Paolo, Brasil, Delhi, India, New York and Corning, America; Expo 1967 in Montreal; and Expo 1970 in Osaka. Each of these events presented, among others, glass created by leading artists from Nový Bor.
