The battle of Sokolovo in 1943 saw the Red Army and Czech forces fighting together to hold back the Nazis. The film is a war film detailing the battle and highlighting the cooperation between the Soviet and Czech forces. Reboiro's poster seems to shy away from the imagery of war altogether and focuses on the blood red flower and 70s colour scheme. There is a possibility that this was one of those days when the artist didn't have time to see the film before he designed the poster. Or Reboiro's flower symbolises the bloody union as two armies joined forces to create bloodshed and massacre in the name of victory. Check out the difference between Reboiro's design and the Czech original below.
