To be honest I do not know the name of this museum in Municipal House or Obecní dům, the stunning Art Nouveau concert venue. It is more a design exhibition, but most of the exhibits are glass, and not all are exhibits, some are on sale, and not only glass, also books and music for sale.
The style is from a particular period of Bohemian glassware. The books were of this period.
The music on sale was of performances in Smetna Concert Hall.
