The ch Foundation for federal cooperation was founded in 1967 as a foundation un- der private law and is sponsored by all 26 Swiss cantons. It is committed to the con- cept of federalism. As a well-connected institution, it also promotes bridge-build- ing between the cantons and different linguistic communities of Switzerland, and provides services for the cantons. The design of the special stamp marking the 50th anniversary of the ch Founda- tion had a speci c mission to ful l – to represent unity in diversity in a contem- porary way. St. Gallen illustrator Sylvia Geel created an illustration using the col- ours and shapes of all 26 Swiss cantonal coats of arms. She broke down the design of the individual coats of arms to create one overall composition that visualizes diversity in unity.
