The American Helvetia Philatelic Society (AHPS) is the largest group for collectors of Swiss stamps outside Switzerland. The current organization dates from 1975 but traces its lineage back to 1938, when six Swiss and three Americans founded the original Society for Collectors of Switzerland in Philadelphia.
Today AHPS offers a full range of services to some 325 collectors primarily in the United States, but also in Canada, Great Britain and Switzerland, from new issue fans to international exhibitors. The society is an important source of information and material on the stamps, postal history and philatelic literature of Helvetia, as this popular European country identifies itself on its stamps.
