A wide variety of Topical collecting interests exist within the OPS membership including Motorcycles, Railways, Bats (Order Chiroptera), Chocolate, Dragons and Pop Culture Villains.


     The Topical Study Group normally meets six to seven times during the OPS year. The group serves as an informal forum for OPS members and guests to share information and learn more about topical and thematic stamps and collecting. Meetings can follow a variety of formats but will normally focus on a facilitated discussion or presentation led by a group member or guest speaker.
