Issued in 1969, this 30 rappen commemorative from Liechtenstein celebrates 100 years of telegraphy (1869–1969). The geometric design features the flags and emblems of Austria, Liechtenstein, and Switzerland, symbolizing the cooperative telegraph network linking the Alpine nations. The modernist block motif, in gold, red, blue, and white, reflects the precision and interconnection of communication systems. Designed by Hans Peter Gassner and printed in photogravure, it’s a fine example of mid-century European graphic design.
