The American Topical Association (ATA) was founded in 1949 and is now the largest philatelic society devoted specifically to topical stamp collecting. Serving members worldwide, we pride ourselves in being the best source of information, fellowship and authority in this field.
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. Read more about ATA membership and its full benefits.
