This coloured optic decorated glass was prpobably very popular on begining of 60ties, see other varieties from my collection.
I have tried to find more about designer Max Kannegiesser, I have got only very limited infos from Mr. Wünsch. Kannegiesser was Bohemian-German, studied in Dresden, during war he was an officer in German army. He worked in Borske sklo in 50ties, on beginning of 60ties he was allowed to leave Czechoslovakia for Germany. He found his new home in Bavaria in glass town Zwiessel.
He has a record in communistic secret police files (5105) STB as secret co-operator with nick name "Harry". Also Mr. Wünsch has mentioned that Kannegiesser was "sent" to Germany with his spy duties. Possibly somebody from our German friends would be able to find more about this leading designer of fifties somewhere at German sites or directly in Zwiessel.
