The Americana Unit was founded in 1951 by a group of members of the American Topical Association who were interested in the study of those stamps from around the world that depict some aspect of "AMERICANA". It could be U.S. Presidents, The U.S. Flag, The Statue of Liberty, Famous Americans, Famous American Landmarks (Mount Rushmore, The Grand Canyon or any philatelic recognition of the history, culture or ideals of the United States of America.

Since 1951 the scope of Americana philately has grown to include the US conquest of space and the bicentennial of the American Revolution and the Bicentennial of the Statue of Liberty. The Americana Unit is the largest and most active philatelic club devoted to the collecting of stamps covers and other philatelic material related to the topic of Americana. In 1972 the Unit affiliated the American Philatelic Society (APS) as Unit number 40.

The unit publishes a quarterly journal called Americana Philatelic News. Each 24 page issue contains feature articles on various Americana topics, new issue listings and officer reports. You are invited to join with other collectors from all parts of the US (and some overseas) who enjoy collecting the topic of AMERICANA.
