Physical Culture and Sports Society (PSS ) Dinamo or Dynamo is an All-Russian fitness-sports society based in Moscow. Stamps were glued to a special booklet to confirm that member of PSS Dinamo has paid his donation (every 3 months usually) to develop the organization. There were many clubs (Dinamo Moscow, Dinamo Riga, Dinamo Leningrad etc.) and these clubs were parts of the PSS Dinamo(USSR). Many of these clubs were known for the excellent ice hockey teams.
