Stamps depicting different elements of blood transfusion have been issued relatively frequently to advertise and promote national blood donation campaigns and to raise funds for transfusion services. The Belgium blood transfusion stamp from 1959 was part of the set of six Red Cross stamps and shows blood dripping from the Red Cross emblem filling the stylised heart. The National Blood Transfusion Service was the theme of the 20 paisa stamp issued by Pakistan in 1972, which also shows the emblem of the Red Cross. Japan issued a stamp featuring world blood donation in 1974 to commemorate International Red Cross Day. The stamp design incorporates the ABO blood groups, the world, and doves of peace.
