Established in 1949 the American Topical Association is the largest philatelic society devoted specifically to topical stamp collecting. Serving members in over 90 countries, we pride ourselves in being the best source of information, fellowship and authority in this field.
Celebrating over 60 years, membership in the ATA includes many benefits like our bi-monthly Topical Time journal, handbooks published on popular collecting topics and checklists useful for those who have started a topical collection, or wishing to start a new collection.
