Midcentury Glass Bell, Czechoslovakia 1960s

Great, unique item with an interesting hostory and purpose. Originally used in Czechoslovakia where it was produced as a part of laboratory set at a University of Natural Science in Bratislava since 1960s. The glass bell was used as a cover for plants at the University. It is made of a heavy, clear glass. The bell is round and really cool looking with an original ball -like handle on top. Excellent condition. One little bubble in the glass, but it must be there since the bell was produced. Excellent condition without damages.
