Soviet Philatelic Association
[1] Two early philatelic public entities existed in the Soviet Union.
These were All-Russian Society of Philatelists (created in 1922) and Philatelic International (or Filintern organised in 1924).
In July 1924, an "All-Union Philatelic Association of Socialist Soviet Republics" was formed.
It lacked a published decree of the All-Russian Central Executive Committee (VTsIK) and RSFSR Sovnarkom.
[1] The SFA organ was the journal Sovetskii Filatelist (Soviet Philatelist).
