8 postcards
For some reason this set only consists of eight postcards, I've no idea why they didn't include the other four stadiums as the stamp sheet only has the eight stadiums too.
Luzhniki Stadium, Moscow
Spartak Stadium, Moscow
Kazan Arena
Fisht Olympic Stadium, Sochi
Volgograd Arena
Ekaterinburg Arena
Rostov Arena, Rostov-on-Don
Samara Arena
