Over more than five decades Shamir brothers worked for dozens of clients in the country: the various arms of government, public institutions, industry, marketing firms, financial institutions, and non-profit organisations. Some of the works were commissioned directly and others were a result of winning a competition. Starting in the 60s Shamir brothers entered the international philately market and designed hundreds of stamps for seventeen countries in Africa, Central America and Asia. In this site we also included works created by them pro bono for non-profit organizations and for family needs.
