People in the UK are fine with such images. Soviet imagery (usually fake cyrillic with reversed capital Rs) makes its way into advertisements and such pretty often.
Most youth will only be vaguely aware of the origins of that style of imagery.
It is a bit weird, now that I think about it. It's a bit like Korean bars being "Hitler themed".
It would have been a lot more weird if they were showcasing actual Manchester City Council workers.
EDIT: Here's a great book about soviet political posters. I won an award at school, and I chose this book. It was handed to me by, I think, Baroness Warnock. I can't remember what she said, but it was kind and funny.
If that image was based on a picture of a Soviet leader then I do think it would be odd.
However, as its clearly based on an image of the Soviet people then I don't associate anything negative or inappropriate with it. After all, a lot of people in the UK still remember that it was mainly the Soviets who defeated the Nazis - resulting in incredible suffering and hardship for the people there.
The red flag, workers holding their tools, ready to fight. Did Manchester become the Soviet Republic of Manchester?
