I agree with Ivo, that caution should be exercised as to value.
Few pieces were actually made by Brychta, who for the most part designed this type of item. Clearly the "Universe" series 1958, designed for the Brussels World "Expo" were the work of Ladislav Ouhrabka. Other series designed by Brychta include:"Aquarium"1934, "Glass Heaven" 1936, "Bethlehem" 1936, and "Cities", 1942. Some of his most interesting personal work comes from the period following his retirement, where fantasy and playfulness led to the creation of weird and wonderfully coloured animals.
Nice item, possibly mid-1930's onward.
