Get Limited-Edition United Nations Souvenir Cards
First issued in 1972, United Nations Souvenir Cards honor this organization's accomplishments and special events. Each card pictures several stamps from a set and includes at least one genuine stamp tied to it with a neat First Day of Issue postmark. Selections vary but the one I looked at had cards honoring health in sports, art, stamp collecting and more. These cards are an interesting and affordable way to explore all the good works of the U.N.
